Copper-clad aluminum wire refers to a wire with aluminum core wire as the main body and a certain proportion of copper layer plated on the outside. It can be used as a conductor for coaxial cables and wire and cable conductors in electrical equipment. The aluminum wire has a small specific gravity, but its welding performance is not good. Therefore, the copper-clad aluminum wire is wrapped with a copper layer on the aluminum wire. This copper-clad aluminum wire can not only take advantage of the small aluminum specific gravity, but also improve the welding performance.
