The product description uses a metallurgical composite process, with an outer layer of highly conductive pure copper and an inner layer of aerospace-grade aluminum core. The copper layer is uniformly coated and tightly bonded without delamination, replacing pure copper round wire. It is available in a full range of specifications and has standard wire diameters.
1.Its specific gravity is much lower than that of pure copper, making it lightweight and reducing transportation and installation costs.
2.Its electrical conductivity is close to that of pure copper, meeting conventional current-carrying requirements;
3.High cost-performance ratio, significantly reducing raw material procurement costs;
4.It has good tensile strength, is not easily broken, and is resistant to bending and creep.
5.The outer copper layer ensures that the welding and oxidation resistance properties are consistent with pure copper.
Application areas include building wiring, civil electrical wires and cables, communication cables, internal wiring for home appliances, motor leads, photovoltaic auxiliary materials, lighting wiring, security monitoring cables, etc.
