Copper is one of the first metals discovered by man, and one of the better pure metals. It has the following characteristics: slightly hard, extremely tough, wear-resistant, good ductility, good thermal and electrical conductivity ,at the same time, the copper alloy has good corrosion resistance, is stable in dry air, durable and can be regenerated. Therefore, the excellent comprehensive properties of copper and copper alloy processing materials have been widely good evaluated in the fields of electronics, machinery manufacturing, communications, automobiles, instrumentation, and military industries.
