CCA （Copper Clad Aluminum）Wire
Product Description
All technology indexes of our leading product CCA have reached the national electronic industry standard (SJ/T11223-2000) and American ASTM B566-93 standard. Its copper layer takes refined copper above 99.97% purity under the cladding welding & drawing method, cladding the plashing copper belt coaxially on the aluminum house main, undergoing many times of drawing and heat treatment, have achieved the need of customers' wire size demand and the technology demand of mechanics and electrics. There forms a stable metallurgy combination between copper layer and aluminum stick heart yarn, and copper layer distributes equality towards the circumferential and portrait direction with good concentricity. It can make the different metal materials become an unseparatable unity, which can be drayed like a single metal, but the ratio between copper and aluminum will change while drawing, but the copper layer volume is relatively stable, with smoothly and round surface, without any defect.
Carrying many characteristics of good conductivity, high strength and strong brazability of copper and low density and easily to process of aluminum, CCA has its own features of density equality of copper layer, high compactness and fine enlonging capacity. This bimetal compound lead can be used into the coaxial cable conductor with high signal transmitted features, and become the widely-used lead in CATV and other high frequency appliances. CCA is also the best choice materials for the coaxial cable conductor and cable wire of many electric equipment.
