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. Aluminum wire has a small specific gravity, but its welding performance is not good. Therefore, the copper-clad aluminum wire can not only take advantage of the small specific gravity of aluminum, but also improve the welding performance. It is suitable for electric power and electrical industry, category level For international and domestic.
Because high-frequency signals have the characteristics of "skin effect", copper-clad aluminum wires and copper-clad steel wires have the same electrical conductivity as pure copper wires when transmitting high-frequency signals (greater than 5MHz).
Unique composite performance: Copper-clad aluminum wire has both the conductivity of copper and the composite characteristics of low density of aluminum; while copper-clad steel wire combines the conductivity of copper with the high strength of steel. Tin-plated copper-clad steel wire exerts the solderability and sulfidation resistance of tin; silver-plated copper-clad steel wire improves electrical conductivity, thermal conductivity, corrosion resistance and oxidation resistance. So it has a wide range of applications.
