Mechanical Resistance Pure Copper Foil C11000 C1221 0.1mm - 1.2mm Thickness For Electric Springs
Copper is copper elemental,because its color is purplish red named.Red copper is industrial pure copper with a melting point of 1083℃, no isomorphic transformation, and a relative density of 8.9, five times that of magnesium. It is about 15% heavier by volume than ordinary steel. Because it has rose red, the surface of the formation of oxidation film after purple, so commonly known as copper, it is a certain amount of oxygen copper, so also known as oxygen-containing copper.
