 (Copper) Shenzhen Xing Peng, copper and aluminum materials plant copper industry pure copper, its melting point is 1083 ° C, with prime heterogeneous change in the relative density of 8.9, for five times that of magnesium. Weighs about 15% than ordinary steel. Its red roses, purple formed on the surface oxide film, it is commonly referred to as copper. It is copper with some oxygen, which is also called the oxygen-containing copper. Copper was purple name. It is not necessarily pure copper, sometimes adding a small amount of deoxidation elements or other elements to improve the material and performance, and therefore classified as copper alloy. Chinese copper processing material composition can be divided into: ordinary copper (T1, T2, T3, T4,), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn,), add a small amount of alloy special elements copper (arsenic, copper, tellurium copper, silver, copper) into four categories. Conductivity and thermal conductivity of copper is second only to silver, widely used to produce electric and thermal conductivity equipment. Copper in the atmosphere, sea water and some non-oxidizing acid (dilute), alkali, salt solution and various organic acids (acetic acid, citric acid), good corrosion resistance for the chemical industry. In addition, copper has good weldability, the cold, made of thermoplastic processing of a variety of semi-finished and finished products. Has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. Thermal conductivity equipment is mainly used for the production of generators, bus, cable, switch gear, transformers and other electrical equipment and heat exchangers, piping, solar heating devices, flat-plate collector. Copper alloys are divided into brass, bronze, copper-nickel alloy three categories. Of copper by a much broader use than pure iron, 50% of the copper electrolytic purification of pure copper for the electrical industry each year. Copper are talking about here, is indeed to be very pure copper 99.95% more than the job. A very small amount of impurities, especially phosphorus, arsenic, aluminum, etc., would greatly reduce the conductivity of copper. Copper in the oxygenated (easily mixed with a small amount of oxygen in the copper) affect the conductivity of copper for the electrical industry in general must be oxygen-free copper. In addition, the crystallization of impurities such as lead, antimony, bismuth, copper will not combine, resulting in heat and crisp, also affect the processing of pure copper. High purity copper, electrolysis refined: the pure copper (blister copper) as the anode, pure copper as cathode copper solution as electrolyte. When the current through the impure copper anode gradually melting pure copper will gradually deposited on the cathode. So derived refined copper; purity of 99.99%. Copper is relatively pure copper, generally similar to copper, electrical conductivity, plastic good, strength, hardness poor. Properties and uses of copper in copper, copper, also known as copper has good electrical and thermal conductivity, plasticity excellent, easy to hot pressing and cold pressure processing is used extensively for manufacturing wires, cables, brushes, electric spark dedicated electrical corrosion of copper require electrical conductivity and good products. The namely Akagane. Of sulfide or oxide copper ore smelting of copper, can be used to mint coins and production of artifacts. Song should be the star "Heavenly Creations? Copper:" Where copper for the world, coming out with baked only have Akagane. Parameters calamine or Japanese lead and turn color as brass; and other drug smelting of copper-nickel alloy ; alum, nitrate and other pharmacists refining bronze; wide tin Participation and the ring of copper; Japanese lead and write ﹝ diarrhea ﹞ bronze. early quality is blindly copper only. "Kuo Mo-jo," Chinese Historical Manuscript Part I, Chapter III II: the composition of their smelting of copper pure, natural trace (0.1-0.2%) impurities, no artificial joined tin or lead into the alloy hardness of copper is poor, but directly after beat can be made into a variety of tools and accessories. "features: high-purity, organized crime, the oxygen content is extremely low. Excellent holes, trachoma, porosity, electrical conductivity, electrical erosion out of the mold surface accuracy by the heat treatment process, the electrode had no direction, suitable for playing fine, fine playing, good thermoelectric Road, processing, scalability, corrosion resistance and weather resistance. Usage: can be used in electrical appliances, distilled building and chemical industries, especially the terminal printed electrical circuit board, wire and masking with the Copperbelt, air cushion, the bus terminal. Electromagnetic switch, pen holder, housing the root plate and so on.
