Copper is a tough, soft, and ductile purple-red and shiny metal. Because it has a rose-red color and is purple after forming an oxide film on the surface, it is generally called copper. It is copper containing a certain amount of oxygen, and thus It is called oxygenated copper. Copper is an industrial pure copper with a melting point of 1083 ° C, no isomeric transformation, a relative density of 8.9, five times that of magnesium. The same volume is about 15% heavier than ordinary steel.

Copper has good weld ability and can be processed into various semi-finished and finished products by cold and thermoplastic processing. 

Brass is an alloy of copper and zinc. Brass made of copper and zinc is called ordinary brass.Brass has strong wear resistance,brass is often used in the manufacture of valves, water pipes, air conditioners and other internal and external machine connection pipes and radiators.
