The conductivity of aluminum alloy is 61.8% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, superior to the pure aluminum standard. But in the same volume, the actual weight of aluminum alloy is about one-third of that of copper. [3] 。 Therefore, the weight of aluminum alloy cable is about half that of copper cable at the same current carrying capacity. Replacing copper cable with aluminum alloy cable can reduce cable weight, installation cost, wear of equipment and cable, and make installation easier.

Aluminum wire refers to its longitudinal full length, and uniform cross section refers to metal linear materials made of pure aluminum or aluminum alloy. The products are processed along the center and delivered in rolls. Cross section shapes include circle, ellipse, square, rectangle, equilateral triangle, regular polygon, etc. It can be divided into pure aluminum wire and alloy aluminum wire according to material. It can be divided into industrial aluminum wire and process aluminum wire according to its use.
