    CopperProcessingProductionUsesCopper (Cu) is a malleable, ductile, reddish metal that melts at 1083176;C. Copper has both a high electric and thermal conductivity. Only silver is a better thermal and electrical conductor. In general, copper has good resistance to corrosion, although when exposed to the environment, the surface of the metal oxidizes to form a light green patina or a black oxide coating.
