Product Introduce

Copper-aluminum composite flat wire is a bimetallic conductive flat wire covered by copper-aluminum, which is a "new conductor material". It not only has excellent conductive properties of copper, but also has the characteristics of low density of aluminum. It is a "strategic emerging industry" supported by China.
The copper-aluminum composite flat wire produced by our company is different from the traditional production processes such as hydrostatic extrusion, rolling pressing, cladding welding, casing rolling and other traditional processes, and adopts the original "horizontal continuous casting and efficient molding - rolling" technology to make the copper-aluminum composite flat wire interface reach a certain metallurgical combination and enhance the shear strength of the interface of the two metals. Ensure the mechanical and electrical properties of the product, improve the stability of the product.
