Containing lower conductive. Less thermal conductivity impurity oxygen trace little effect on the conductivity. Thermal and processing properties, but easy to cause a "hydrogen disease", not processing (annealing at high temperatures (eg> 370 °) reducing atmosphere welding, etc.) and the use of copper is pure copper, the melting point of 1083 ℃, no allotropic transformation, the relative density of 8.9g / cm3, magnesium five times. Quality with a weight of about 15 percent by volume than ordinary steel. Because of its red roses after the oxide film formed on the surface was purple, it is commonly known copper. It is with a certain oxygen copper, which is also called an oxygen-containing copper. Its inner impurities are oxidized exhaust, which is conducive to reducing the amount of solid solution conductivity of copper, can eliminate the effects of harmful impurities, but copper prone to embrittlement at 370 ° C or more in a reducing atmosphere (called hydrogen disease). Of copper grades are T1, T2, T3 three, including the extensive use of the T2 copper. T1, T2, T3 copper is based on the different chemical composition and division. T1 copper copper content of more than 99.95%, total impurities not more than 0.05%; T2 copper over copper content of 99.90%, total impurity content of not more than 0.1%; T3 copper copper content of 99.7% total impurities of no more than 0.3% . Copper appearance of purple, with a high electrical conductivity, thermal conductivity, good corrosion resistance and ease of processing. Thus, depending on the uses to be processed into sheet, strip, foil, pipe, bar, wire, rod, copper and bronze pieces of the opposite sex. T2 copper plate belongs to the copper sheet. Copper row and sometimes a small amount of deoxygenated elements or other elements to improve the material and performance. Yunnan Copper Copper is a professional production, marketing, processing of metal materials manufacturers, the introduction of Germany advanced testing and production equipment, professional R & D team and large production capacity. Founded in 1994, the company plant area of ??25,000 square meters, on production of 300 tons of large metal materials production enterprises, in line with Chinese GB, American ASTM, JIS in Japan and other specifications, has been ISO9001, IS09002 certification, all manufactured products have ROHS directive SGS report and material proof. The main production and management products.
