      Related properties and application characteristics of copper-clad aluminum

      The copper clad steel wire adopts the advanced cladding welding manufacturing technology to coat the high-quality copper strip concentrically on the outer surface of the aluminum rod or steel wire core wire, and form a solid metallurgical bond between the copper layer and the core wire. In the process of drawing, copper and aluminum can be reduced in the same proportion, while the volume ratio of copper layer remains relatively constant.
