Copper
Copper is a rose-red metal, and it turns purple after a copper oxide film is formed on the surface, so industrial pure copper is often called red copper or electrolytic copper. The density is 8-9g/cm3 and the melting point is 1083°C. Pure copper has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity and is often used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses, aviation instruments, etc.; excellent plasticity, easy to heat Pressed and cold pressed, it can be made into copper materials such as pipes, rods, wires, strips, strips, plates, foils, etc.
