Are red copper and red copper a kind of copper

Red copper is rose red metal, the surface of the formation of oxide copper film after purple, so industrial pure copper often said copper or electrolytic copper. 99-99.9% pure copper can be obtained by fire refining, and 99.95-99.99% pure copper can be obtained by electrolysis. The density is 8-9g/cm3, and the melting point is 1083°C. Pure copper conductivity is very good, a lot of used in the manufacture of wire, cable, brush, etc. Good thermal conductivity, commonly used to manufacture magnetic instruments and instruments to prevent magnetic interference, such as compass, aviation instruments; Excellent plasticity, easy hot pressing and cold pressure processing, can be made into tubes, rods, wires, strips, strips, plates, foils and other copper materials. Pure copper products are smelted and processed products.
