0.05mm*50mm Pure Copper Foil C11000 C1221 foil CW004A foil for
Mobile phone main board
Copper is copper elemental,because its color is purplish red
named.Red copper is industrial pure copper with a melting point of
1083ºC, 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.
