What are the characteristics of copper core cable and aluminum core cable

【China Aluminum Industry Co., Ltd.】 Copper core cable is an ideal conductor material because of its high conductivity, high mechanical strength, easy processing, welding, convenient construction, and corrosion resistance. The aluminum core cable has a lower conductivity than copper, and the aluminum has a small specific gravity. The mechanical strength of the aluminum core cable is worse than that of the copper core, the aluminum resources are wide, the price is low, and the connection of the aluminum core cable is more complicated than the copper. In particular, the aluminum surface is prone to oxide film and affects the welding.
