Strength and hardness for each individual alloy is increased by cold working; they are not hardened by heat treatment. It is one of only four elements that are ferromagnetic at or near room temperature; the others are iron, cobalt and gadolinium.Its Curie temperature is 355 C (671 F), meaning that bulk nickel is non-magnetic above this temperature. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. [4] In 1911, Franois Auguste Roux of L'Aluminium Franais patented the process (using both hypophosphite and orthophosphite) for general metal plating. [25], The alloy seems to have been rediscovered by the West during alchemy experiments. Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. strength. Another common 20th-century use of cupronickel was silver-coloured coins. [26], In 1829, Percival Norton Johnston persuaded Dr. Geitner to establish a foundry in Bow Common behind Regents' Park Canal in London, and obtained ingots of nickel-silver with the composition 18% Ni, 55% Cu and 27% Zn.[26]. Make sure this fits by entering your model number. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress corrosion cracking in most freshwaters combined to its resistance to a variety of corrosive conditions justifies its wide use in marine applications and other non-oxidizing chloride solutions. )Despite its high copper content, cupronickel is silver in colour. Thermocouples and resistors whose resistance is stable across changes in temperature contain alloy constantan, which consists of 55% copper and 45% nickel. Barron Industries is a Tier 1 supplier to the worlds leading heavy truck manufacturers. Unlike electroplating, electroless plating processes in general do not require passing an electric current through the bath and the substrate; the reduction of the metal cations in solution to metallic is achieved by purely chemical means, through an autocatalytic reaction. This procedure was initially developed by Odekerken in 1966 for electrodeposited nickel-chromium coatings. Brass. Martin & Co. uses Monel for their Martin Retro acoustic guitar strings. 0000001565 00000 n We welcome your questions and are ready to solve your biggest challenges. Monel 404 is used in capsules for transistors and ceramic to metal seals and other things. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as [18], Oilfield applications include using Monel drill collars. The first commercial application of their work was electroless nickel-silicon carbide coatings on the Wankel internal combustion engine. 0000001447 00000 n It is resistant to corrosion and acids, and some alloys can withstand a fire in pure oxygen. For example, in 2015 Monel piping was three times more expensive than the equivalent piping made from carbon steel.[8]. Monel K-500 combines the excellent corrosion resistance characteristic of Monel alloy 400 with the added advantages of greater strength and hardness. It can be used to apply composite coatings, by suspending suitable powders in the bath. [3], Compared to the electrolytic process, a major advantage of electroless nickel plating is that it creates an even coating of a desired thickness and volume, even in parts with complex shape, recesses, and blind holes. We have extensive proprietary knowledge of gas and chemical delivery systems, and advanced reactor process equipment, We support the semiconductor capital equipment industry with critical subsystems and engineering solutions, With our technical expertise and global capacity, we are a turn-key partner to major original equipment manufacturers (OEMs), Our capabilities enable the design and creation of a complete outsourced solution. 0000002409 00000 n This is in marked contrast to many ferrous materials which are brittle at low temperatures despite their increased Like Monel 400, alloy R-405 is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. When a crust of slag formed, saltpeter was added, the alloy was stirred and the ingot was immediately cast. Notwithstanding what is here said, of the colour of the copper being owing to no mixture, it is certain the Chinese white copper as brought to us, is a mixt [sic: mixed] metal; so that the ore from which it was extracted must consist of various metallic substances; and from such ore that the natural orichalcum if it ever existed, was made."[25]. C360 is also known as Free-Cutting and Free-Machining brass because it has a 100% machinability rating, and is the standard C36500 Leaded Muntz. Monel 404 can be welded using common welding techniques and forged but cannot be hot worked. In 1968, Switzerland adopted the far cheaper 75:25 copper to nickel ratio then being used in Belgium, the United States and Germany. On substrates that are not metallic but are electrically conductive, such as graphite, the initial layer can be created by briefly running an electrical current through it and the bath, as in electroplating. Metalits time to meet your maker. Barrons complete vertically integrated process includes additive manufacturing techniques that allow us to produce a precision-machined rapid prototype casting in as little as ten days. Wall Colmonoy is the forerunner in the manufacture and development of Nicrobraz nickel-based brazing products. At the same time, the Prussian Verein zur Befrderung des Gewerbefleies (Society for the Improvement of Business Diligence/Industriousness) offered a prize for the mastery of the process. [14], The processes for electroless nickel-phosphorus plating can be modified by substituting cobalt for nickel, wholly or partially, with relatively little changes. The age-hardenable copper-nickel-silicon alloys with 1.0 to 4.5% Ni and 0.2 to 0.6% Be are not dealt with here. But in De Natura Metallorum in Singalarum Part 1, published in 1599, the same term was applied to "tin" from the East Indies (modern-day Indonesia and the Philippines) and given the Spanish name, tintinaso.[25]. Monel is typically much more expensive than stainless steel. Monel is used for safety wiring in aircraft maintenance to ensure that fasteners cannot come undone, usually in high-temperature areas; stainless wire is used in other areas for economy. In recreational boating, Monel is used for wire to seize shackles for anchor ropes, for water and fuel tanks, and for underwater applications. However, it is first mentioned specifically by name in the Thien Kung Khai Wu of circa 1637: "When lu kan shih (zinc carbonate, calamine) or wo chhein (zinc metal) is mixed and combined with chih thung (copper), one gets 'yellow bronze' (ordinary brass). accelerators, such as certain sulfur compounds, to counteract the reduction of plating rate caused by complexing agents. Since cupronickel is much softer than steel, it bends and flares more easily, and the same property allows it to form a better seal with hydraulic components. [15], Cupronickel is used in cryogenic applications. Copper-Nickel-Alloys: Properties, Processing, Applications, Copper-Nickel Alloys for Seawater Corrosion Resistance and Antifouling - A State of the Art Review, https://en.wikipedia.org/w/index.php?title=Cupronickel&oldid=1125572372, Short description is different from Wikidata, Articles with unsourced statements from July 2020, Creative Commons Attribution-ShareAlike License 3.0. [3], The reduction of nickel salts to nickel metal by hypophosphite was accidentally discovered by Charles Adolphe Wurtz in 1844. Typical materials that can be centrifugal cast are metals, cements, concretes, glass, and pottery materials. From simple to complex shapes, investment castings are the ideal solution for both prototype and production requirements. Monel has also been used in Kelvinator refrigerators. [1], The 19911996 Acura (Honda) NSX came with a key made of Monel. The New York Times on August 12, 1915 published an article about a 215-foot yacht, "the first ship that has ever been built with an entirely Monel hull," that "went to pieces" in just six weeks and had to be scrapped, "on account of the disintegration of her bottom by electrical action." [25] Cammann criticized Cheng and Schwitter's paper, arguing that the decline of cupronickel currency should not have coincided with the opening of the Silk Road. Resistance welding is a very satisfactory method for joining the material. ; Related Documents . You must have JavaScript enabled in your browser to utilize the functionality of this website. The specific characteristics vary depending on the type of EN plating and nickel alloy used, which are chosen to suit the application. However, the Schneeberg district of Germany, where the famous Blaufarbenwerke made cobalt blue and other pigments, solely held the requisite complex cobalt-nickel-arsenic ores in Europe. [16] During the world wars, Monel was used for US military dog tags. Barron Industries Named Michigan Works Business of the Year. Monel is used by Arrow Fastener Co., Inc. for rustproof T50 staples. Barron Industries is a trusted partner to leading ground-based defense GF&P is a full service fabrication, machining, and electroplating job shop, providing finished components to a wide classification of manufacturers. 0000000839 00000 n The copper content typically varies from 60 to 90 percent. Its combination of good ductility retention and thermal conductivity at very low temperatures is advantageous for low-temperature processing and storage equipment as well as for heat exchangers at cryogenic plants.[16][17][18]. Granted on 1950-12-05, expired on 1967-12-05. Full membership to the IDM is for researchers who are fully committed to conducting their research in the IDM, preferably accommodated in the IDM complex, for 5-year terms, which are renewable.

Copper-nickels naturally form a thin protective surface layer over the first several weeks of exposure to seawater and this provides its ongoing resistance. In attempting to rediscover the secret of white-copper, Watson critiqued Jean-Baptiste Du Halde's History of China (1688) as confusing the term paktong'., He noted the Chinese of his day did not form it as an alloy but rather smelted readily available unprocessed ore: "appeared from a vast series of experiments made at Peking- that it occurred naturally as an ore mined at the region, the most extraordinary copper is pe-tong or white copper: it is white when dug out of the mine and even more white within than without. Aside from cupronickel and copper-nickel, several other terms have been used to describe the material: the tradenames Alpaka or Alpacca, Argentan Minargent, the registered French term cuivre blanc, and the romanized Cantonese term Paktong, (the French and Cantonese terms both meaning "white copper"); cupronickel is also occasionally referred to as hotel silver, plata alemana (Spanish for "German silver"), German silver, and Chinese silver. Some alloys, such as electruman alloy of silver and goldoccur naturally. Coatings of 25 to 100 micrometers can be applied and machined back to the final dimensions. However, the Pha Phu Tsu and the Shen I Ching describing a statue in the Western provinces as being of silver, tin, lead and Tanyang copper which looked like gold, and could be forged for plating and inlaying vessels and swords. This page was last edited on 11 October 2022, at 18:31. If the Bactrian nickel theory were true, according to Cammann, the Silk Road would have increased the supply of cupronickel. What began as a Detroit foundry producing 60 ton sand castings has evolved into a global precision casting company with the most advanced vertically- integrated manufacturing processes. Investment Castings. If the substrate is not made of one of those metals, then a thin layer of one of them must be deposited first, by some other process. [14], A thermocouple junction is formed from a pair of thermocouple conductors such as iron-constantan, copper-constantan or nickel-chromium/nickel-aluminium. Monel 502 is a nickel-copper alloy and its UNS no is N05502. Our products include the gas and chemical delivery subsystems that are key elements in the process tools used for commercial semiconductor device manufacturing. The composition of the coins was later verified using the traditional wet method and X-ray fluorescence spectrometry. Details of fabrication procedures, including general handling, cutting and machining, forming, heat treatment, preparing for welding, weld preparations, tack welding, welding consumables, welding processes, paintina, mechanical properties of welds, and tube and pipe bending are available. [1] It is the most common version of electroless nickel plating (EN plating) and is often referred by that name. The magnetic layers are then deposited on top of this film, usually by sputtering and finishing with protective carbon and lubrication layers. Challenge Barron Industries embraced the challenge. Thus electroless plating creates an even layer of metal regardless of the geometry of the surface in contrast to electroplating which suffers from uneven current density due to the effect of substrate shape on the electric resistance of the bath and therefore on the current distribution within it. Alloy R-405 is chiefly used for automatic-screw-machine stock and is not generally recommended for other applications. Brass is an alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. The alloy does not undergo a ductile-to-brittle transition even when cooled to the temperature of liquid hydrogen. [16], Another major advantage of EN plating is that it does not require electrical power, electrical apparatuses, or sophisticated jigs and racks. McMaster-Carr is the complete source for your plant with over 700,000 products. One setup, multiple processes, unlimited efficiency. Descending the table, the maximum allowable flow rate in piping increases, as does the tensile strength. Barron Industries manufactures precision investment castings with custom ferrous and non-ferrous metals. Electroless plating has many industrial applications, from merely decorative to the prevention of corrosion and wear. Geitner and J.R. von Gersdoff of Schneeberg won the prize and launched their "German silver" brand under the trade names Argentan and Neusilber (new silver). As nickel and copper are mutually soluble in all proportions, it is a single-phase alloy. [26] Cupronickel became widely understood, as published by E. Thomason, in 1823, in a submission, later rejected for not being new knowledge, to the Royal Society of Arts. However, the co-deposition of diamond and PTFE particles was more difficult than that of aluminum oxide or silicon carbide. Cold working may be done using standard tooling and soft die materials for better finish.

[16], Porosity decreases as the phosphorus contents increases, while hardness, wear resistance, and resistance to corrosion increase. Typical metals cast are iron, steel, stainless steels, and alloys of nickel, aluminum, and copper, magnesium.. Two materials can be combined by introducing a second material during the process. Call us today! The corrosion resistance of Monel alloy K-500 is substantially equivalent to that of alloy 400 except that, when in the age-hardened condition, alloy K-500 has a greater tendency toward stress-corrosion cracking in some environments. It needs to be turned and worked at slow speeds and low feed rates. Lets cover the most common post-processing techniques. The coatings were claimed to be "an intimate dispersion of hard trinickel boride (.mw-parser-output .template-chem2-su{display:inline-block;font-size:80%;line-height:1;vertical-align:-0.35em}.mw-parser-output .template-chem2-su>span{display:block;text-align:left}.mw-parser-output sub.template-chem2-sub{font-size:80%;vertical-align:-0.35em}.mw-parser-output sup.template-chem2-sup{font-size:80%;vertical-align:0.65em}Ni3B) or nickel phosphide (Ni3P) in a soft matrix of nickel and thallium". After applying each bath, the surface must be thoroughly rinsed with water to remove any residue of the cleaning chemicals. SME has in-house machining shop, an experienced team of professionals ensuring that customer needs are met on time. However, the end of Greco-Bactrian cupronickel currency could be attributed to other factors such as the end of the House of Euthydemus. Ichor is the leader in the design, engineering and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment. Read More From 1947 to 2012, all "silver" coinage in the UK was made from cupronickel, but from 2012 onwards the two smallest cupronickel denominations were replaced with lower-cost nickel-plated steel coins. Weve acted like this since 1982 and continue to look forward to serving leading companies in multiple industries for decades to come. [emailprotected], 2022 Barron Industries | Powered by Momentum. Our high-strength components withstand high temperatures and high pressure working environments. 0000001289 00000 n [1][6], In 1969, Harold Edward Bellis from DuPont filed a patent for a general class of electroless plating processes using sodium borohydride, dimethylamine borane, or sodium hypophosphite, in the presence of thallium salts, thus producing a metal-thallium-boron or metal-thalium-phosphorus; where the metal could be either nickel or cobalt. E-Fab has operated under the guiding principles of innovation, expertise, and experimentation since our earliest days. [citation needed]. [13], In seabird research, and bird banding or ringing in particular, Monel has been used to make bird bands or rings for many species, such as albatrosses, that live in a corrosive sea water environment.[14]. We utilize our design and manufacturing capabilities to provide functional, affordable, lightweight precision cast hardware components for the space industry. Compared to steel, Monel is very difficult to machine as it work-hardens very quickly. Alloys ranging in composition from 90% Cu10% Ni to 70% Cu30% Ni are commonly specified in heat exchanger or condenser tubes in a wide variety of marine applications.[4]. Johnsons' most serious competitors, Charles Askin and Brok Evans, under the brilliant chemist Dr. EW Benson, devised greatly improved methods of cobalt and nickel suspension and marketed their own brand of nickel-silver, called "British Plate".[26]. They can be fabricated readily by hot- and cold-working, machining, and welding.[2]. A 'puritan' alloy is one whose main constituents are supplied from a base ore with the same composition, thus not requiring to be blended with material from another ore. "Robert Crooks Stanley (1876-1951) The Grandfather of the nickel industry (Part 1 of 2)", "Monel 400 (NiCu30Fe, 2.4360, N04400, NA13):: MakeItFrom.com", "New York Times, August 12, 1915: Big Yacht Now Junk After Six Weeks Use", "The Clock of the Long Now A Reflection", https://en.wikipedia.org/w/index.php?title=Monel&oldid=1122925205, Short description is different from Wikidata, Articles with unsourced statements from January 2019, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 20 November 2022, at 17:27. Ed Fagan Inc. is proud that our locations in Franklin Lakes, NJ and Los Alamitos, CA operate a Quality Management System that meets the requirements of ISO 9001:2015 and AS9100D for precision cutting, deburring and distribution of specialty metals and alloys. Machining Punched. Coatings with more than 10% phosphorus are amorphous. Often referred to as precision castings, investment castings reduce the high cost of machined parts, fabrications and assemblies. Unlike pure tungsten, heavy alloy can be conventionally machined and is less expensive. Harold Edward Bellis (1969): "Nickel or cobalt wear-resistant compositions and coatings". These will sometimes include a Monel manifold and taps prior to the regulator that allow the regulator to be flushed with a dry, inert gas after use to further protect the equipment. Monel alloy K-500 has been found to be resistant to a sour-gas environment. Cupronickel has been used as an alternative to traditional steel brake lines, as it does not rust. [10][11][12], A declassified US Army technical report in 1963 credits the discovery to Wurtz and Roux more than to Brenner and Riddell. ; Material Properties - Material properties of gases, fluids and solids - densities, specific heats, viscosities and more. Stamping & Forming Swiss CNC Turning. The yacht's steel skeleton deteriorated due to electrolytic interaction with the Monel. JavaScript seems to be disabled in your browser. It is a nickel-copper alloy with a controlled amount of sulfur added to provide sulfide inclusions that act as chip breakers during machining. Monel is used in motion picture film processing. The junction may be protected within a sheath of copper, cupronickel or stainless steel. Videos & Images. Your Distributor for Hard-to-Find Aerospace, Defense and Medical Metals. Monel offers exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. Monel 502 can be formed in different shapes. Solid-solution binary alloy of nickel and copper. %PDF-1.4 % Some weapons made during the Warring States period were made with Cu-Ni alloys. Welded. Our engineers, manufacturers, and quality assurance specialists turn ideas into precision parts through collaboration, engineering, and expert machining processes. [citation needed], Its use in the automotive industry for wear resistance has increased significantly. Griner Engineering, Inc. has been in business since 1978 supplying precision-machined components and services to transportation and other markets requiring high levels of quality, service, and competitive cost. For nickel-boron coatings, see. This included large decorative screens, doorknobs, etc. [16], Electroless nickel plating also can produce coatings that are free of built-in mechanical stress, or even have compressive stress.[16]. Machining. [16], If properly formulated, EN plating may also provide a less porous coating, harder and more resistant to corrosion and hydrogen absorption. Zinc is mentioned as an ingredient but there are no details about when it was added. Prior to these dates, both denominations had been made only in silver in the United States. There are many post-processing methods that can be applied to both 3D printing and CNC machining to improve the functional and cosmetic qualities of parts. Global automotive OEMs and Tier 1 suppliers turn to Barron Industries as their trusted source for turnkey manufacturing of complex precision castings and engineered sub-assemblies. Carbon and Low-Alloy Steel Investment Castings, Best Investment Castings Award Winner for 3. Monel is a solid-solution binary alloy. Sakiewicz P.,Nowosielski R., Babilas R. Production aspects of inhomogeneous hot deformation in as-cast CuNi25 alloy, Indian Journal of Engineering & Materials Sciences, Vol. Stockist of boiler/ heat exchanger tubes in UAE. Both locations are temperature-controlled warehouses specifically designed to ensure protection of Our safety-critical castings are built to withstand the most rigorous high-demanding industrial applications. 0000001670 00000 n [26] The nickel, carbon, manganese, iron, silicon & copper percent remains the same as alloy 400, but the sulfur is changed from 0.024 max to 0.025-0.060%. [25] Cunningham in 1873 proposed the "Bactrian nickel theory," which suggested that the coins must have been the result of overland trade from China through India to Greece. Moreover, the Yunnanese State of Tien was founded in 334 BC as a colony of the Chu. The author-scholar, Ho Wei, precisely described the process of making cupronickel in about 1095 AD. Cupronickel tubing can be readily expanded into tube sheets for the manufacturing of shell and tube heat exchangers. E-Fab continues to invest in our people and technology to layer in new capabilities and better serve our clients. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel. Other uses include military equipment and chemical, petrochemical, and electrical industries.[1]. "[25], Ko Hung stated in 300 AD: "The Tanyang copper was created by throwing a mercuric elixir into Tanyang copper and heated- gold will be formed." As a turnkey partner to major original equipment manufacturers (OEMs), Ichors customers are able to outsource all non-critical elements of their tool design, production and support in order to focus their resources on process and technology development. Cleaning is usually achieved by a series of chemical baths, including non-polar solvents to remove oils and greases, as well as acids and alkalis to remove oxides, insoluble organics, and other surface contaminants. Monel staple splices are ideal for resisting corrosion from use in continuous-run photochemical tanks. Coins of a similar alloy with busts of his younger brothers, Pantaleon and Agathocles, were minted around 170 BCE. [16], The melting point of the nickel-phosphorus alloy deposited by the EN process is significantly lower than that of pure nickel (1445 C), and decreases as the phosphorus content increases, down to 890 C at about 14% P.[16], The magnetic properties of the coatings decrease with increasing phosphorus contents. Our commitment to service and problem-solving starts by listening to what problems our customers are trying to solve and the challenges they are facing. This grade also has good creep and oxidation resistance. The alloy is also resistant to many forms of sulfuric and hydrochloric acids under reducing conditions. Many complexing agents act as buffers. G. O. Mallory and J. 0000000686 00000 n Monel is often traded under the ISO standards 6208 (plate, sheet and strip) 9723 (bars) 9724 (wire) 9725 (forgings) and the DIN 17751 (pipes and tubes). Cupronickel lacks a copper color due to nickel's high electronegativity, which causes a loss of one electron in copper's d-shell (leaving 9 electrons in the d-shell versus pure copper's typical 10 electrons). Thereafter all those who prepared chemical powders by heating and transmuting copper by projection called their methods "Tanyang techniques".[25]. [i][4][5] Monel was named after company president Ambrose Monell, and patented in 1906. Customers rely on Ichor to continually improve product costs, quality, and lead times with expanded services, resulting in numerous Supplier-of-the-Year awards from leading OEMS. Notably, Andreas Libavius, in his Alchemia of 1597, mentions a surface-whitened copper aes album by mercury or silver. The ore used is noted as solely available from Yunnan, according to the story: "San Mao Chun were at Tanyang during a famine year when many people died, so taking certain chemicals, Ying projected them onto silver, turning it into gold, and he also transmuted iron into silver thus enabling the lives of many to be saved [through purchasing grain through this fake silver and gold] Monel is also used as a protective binding material on the outside of western style stirrups. CNC machining: Bead blasting, anodizing (Type II & Type III), powder coating [2], Cupronickel alloys are used for marine applications[3] due to their resistance to seawater corrosion, good fabricability, and their effectiveness in lowering macrofouling levels. At Metals Unlimited Aerospace, Inc., we specialize in the hard-to-find materials other companies cant locate. They can also be welded directly to steel, providing a 65% nickel-copper weld consumable is used to avoid iron dilution effects. 22, August 2015, pp. seagrasses and molluscs) living in the seawater. +1 (248) 628-4300 Typical applications for alloy K-500 are pump shafts and impellers, doctor blades and scrapers, and oil-well drill collars, instruments, and electronic components. [6][7], Brenner and Riddel presented their discovery at the 1946 Convention of the American Electroplaters' Society (AES);[8] a year later, at the same conference they proposed the term "electroless" for the process and described optimized bath formulations,[9] that resulted in a patent. Manganese Phosphate Passivation Zinc Phosphate Fabricating & Machining. Easily soldered and brazed and has very good resistance to corrosion. Monel is a group of alloys of nickel (from 52 to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. The nickel-copper sulfides resulting from the sulfur in its composition act as chip breakers, but because of these inclusions the surface finish of the alloy is not as smooth as that of alloy 400. By changing the baths, the procedure can create coatings with multiple layers of different composition. If the substrate is a metal that is more electropositive than nickel, such as iron and aluminum, an initial nickel film will be created spontaneously by a redox reaction with the bath, such as:[1]. [citation needed], Elecroless nickel plating, covered by a thin layer of gold, is used in the manufacture of printed circuit boards (PCBs), to avoid oxidation and improving the solderability of copper contacts and plated through holes and vias. Currently, cupronickel and nickel silver remain the basic material for silver-plated cutlery. US Patent 2532283. LEARN MORE Stainless, aluminum, mild steel and more. It appears, by a vast number of experiments made at Peking, that its colour is owing to no mixture; on the contrary, all mixtures diminish its beauty, for, when it is rightly managed it looks exactly like silver and were there not a necessity of mixing a little tutenag or such metal to soften it, it would be so much more the extraordinary as this sort of copper is found no where but in China and that only in the Province of Yunnan".
