Tinned Copper Covered Aluminium

Tinned Copper Covered Aluminium

Tinned copper covered aluminum is made by coveering a coating of tin on the surface of copper clad aluminum wire by hot dip method, which 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 metaliurgy combination between copper coating and aluminum. There will be no flaking off during the heat treatment or mechanical workout. The TCCA is a best new clad metal wire instead of pure copper wire. Producible scope: the diameter is from Φ0.10mm to 1.20mm.


Product Fearures: shiny & uniformity tin 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 signal 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.
