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, so the aluminum wire is wrapped with a copper layer. This copper-clad aluminum wire can not only take advantage of the small specific gravity of aluminum, but also improve the welding performance. Applicable to electric power and electrical industry. The service life of copper clad aluminum is similar to that of pure copper wire, which is about 20 years. Because the main function of this kind of wire is to transmit signals, the current flowing through it is very small. However, since the conductivity of aluminum is only 2/3 of that of copper, the national standard stipulates that all wires and cables used to transmit electrical energy must use unplated or metal-plated annealed copper wires as conductors, and aluminum wires (including copper-clad aluminum) are prohibited. wire) as a conductor. It has good corrosion resistance: aluminum is easier to corrode than copper, but because the copper-clad aluminum material has been completely metallurgized, the aluminum is completely covered by copper, and will not be contacted by water and air, which fully achieves the same performance as copper. Good weldability: The copper-clad aluminum wire has the same weldability as the pure copper wire because its surface is concentrically coated with a layer of pure copper, which is convenient for production.
