First of all, it is in the welding process is different. Ting extensibility strength is different, determining the direction of the products made is different. Physical properties are different, conductivity is different, specific gravity is different, the price difference. As the three are too different, the surface treatment is also great: copper, aluminum sheet metal is generally oxidized or plated. Cold rolled sheet metal parts are handled in many ways, in addition to oxidation and plating, as well as spraying, oil spraying, etc.
