Copper Covered Aluminium

copper covered aluminium

The CCA wire is made up by using pure aluminum wire as core. It adopts the advanced coating and welding technology in the world. Plating copper concentrically on the concentric line of aluminum, realizes metallurgy combination between copper coating and aluminum. Threr will be no falking off during the heat treatment or mechanical workout. the CCA is a best new bimetal wire instead of pure copper wire. Producible scope:t the diameter is from Φ01.0mm to Φ3.00mm.


Product Fearures: shiny & uniformity unlform copper layer, excellent electrical conductivity, bear bending, good tensile strength, excellent welding and corrosion, with the great light specific gravity, and savings resources of copper.


Main Application: flexible coaxial cable, a variety of audio and video cable,vehicle single cable, network cable,data transmission cables and so on. Can be used in the above cables: cable conductor, braiding and shielding, the single wire conductor and other conductors. Applicable to a variety of electronic components' lead wire, such as capacitors, resistors and so on.
