Widely usage 12mm copper sheet 
Pure copper, as the name implies, is the highest copper content of copper, because the color purple is also known as red copper, the main component is copper and silver, content of 99.5 ~ 99.95%;  Main impurity elements: phosphorus, bismuth, antimony,, iron, nickel, lead, tin, sulfur, zinc, oxygen, etc.  Used for making conductive equipment, advanced copper alloy, copper base alloy.
Pure copper is rose red metal, the surface of the formation of copper oxide film is purple, 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 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
