Copper-clad aluminum wire is composed of aluminum core wire and tightly coated copper layer, and has the advantages of good electrical conductivity of copper and light weight of aluminum, is the inner conductor of coaxial cable and electrical equipment wire and cable material, can be processed with the same process as pure copper wire cable.

1. GB/T 29197-2012 "Copper clad aluminum wire", the United States ASTMB566-93 "copper clad aluminum wire"

2. copper-clad aluminum wire is divided into soft (A) and hard (H) two kinds according to mechanical properties; According to the copper layer volume ratio of 10% and 15% two kinds

1. Unique compound performance.

2. Copper-clad aluminum wire has the composite characteristics of copper conductivity and low density of aluminum.

3. Obvious economic benefits.

The density of copper-clad aluminum is only 37-40% of that of pure copper wire, and its length is 2.45-2.65 times that of pure copper wire of the same quality and diameter. Its tensile strength is 1.6-2 times higher than that of pure copper wire. Therefore, the use of the length or strength of the wire to produce wire and cable will greatly reduce production costs.
