CCA Bi-Metal Copper Clad Aluminum WireThe CCA Bi-Metal Copper Clad Aluminum Wire produced by Henan Chalco is different from the traditional hydrostatic extrusion,rolling and splicing, cladding welding and sleeve rolling. The original "horizontal continuous casting and high efficiency forming-rolling" technology is adopted to achieve a certain metallurgical bonding between the copper clad aluminium wire and the aluminium clad wire and to strengthen the two metals. The interface shear strength ensures the mechanical and electrical properties of the product, and improves the stability of the product.
The CCA Bi-Metal Copper Clad Aluminum Wire is composed of aluminum core wire and outer copper layer which is tightly clad. It has the advantages of good conductivity of copper and light weight of aluminum. It is the preferred material for inner conductor of coaxial cable and cable in electrical equipment. The same process cable can be used for pure copper wire.
