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, which 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. Because the main function of this kind of wire is to transmit signals, the current flowing through it is very small.

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. For aluminum conductors, especially in coastal areas, the chloride ions contained in the salt mist in the atmosphere will condense on the surface of aluminum, which is easy to cause local corrosion around impurities and defects on the surface, forming holes, cracks and micro-batteries, and aggravating the corrosion of aluminum conductors .
