Copper wire, also known as copper is the quality of copper, because its color is purple and named. See a variety of properties of copper. Copper is an industrial pure copper, the melting point of 1083 ℃, no allogeneic transformation, the relative density of 8.9, five times the magnesium. The mass of the same volume is about 15% heavier than that of ordinary steel. Because of its red rose, the surface of the oxide film formed after the purple, it is generally known as copper. It is a certain oxygen containing copper, which is also known as oxygen-containing copper.red copper wire is named after the purple. It is not necessarily pure copper, sometimes adding a small amount of deoxidizing elements or other elements to improve the material and performance, it is also classified as copper alloy. China's copper processing materials 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 Elements of the special copper (arsenic copper, tellurium copper, silver copper) four categories. Copper conductivity and thermal conductivity second only to silver, widely used in the production of conductive, thermal equipment. Copper in the atmosphere, sea water and some non-oxidizing acid (hydrochloric acid, dilute sulfuric acid), alkali, salt solution and a variety of organic acids (acetic acid, citric acid) in good corrosion resistance for the chemical industry.
brass wire has good electrical conductivity, thermal conductivity, corrosion resistance and processing performance, can be welded and brazed. Containing less conductive, less thermal conductivity impurities, trace oxygen on the conductivity, thermal conductivity and processing performance has little effect, but easy to cause "hydrogen disease", not in high temperature (such as> 370 ℃) reducing atmosphere processing (annealing, Welding, etc.) and use.
