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.Copper is an aggregate composed of fossils or oxides and other minerals. Different proportions of each component will produce different grades of copper structures with different performance characteristics. To improve product performance, surface treatments can also be used to enhance corrosion resistance, wear resistance or aesthetics. Common grades and surface treatment are as follows. Engineers can make corresponding choices according to their needs.
