Product Introduction

Copper clad aluminum magnesium alloy wire(CCAM) is a new type high strength product developed on the basis of copper-clad aluminum wire. It is a bimetallic wire with aluminum-magnesium alloy wire as the core and a copper layer as the outer layer. It is widely used in coaxial cable braid layer, audio and video cable conductor and braid layer, etc.

We can provide copper-clad aluminum-magnesium alloy wire by both electroplating method and cladding method.

The electroplating method uses the principle of electrode-position to coat the surface of the aluminum-magnesium alloy wire with a copper layer in a solution of a copper salt. The electroplated wire blanks are then drawn and heat treated to become copper-clad aluminum magnesium wire of varies specifications and properties.

The cladding method is to pretreat the aluminum-magnesium alloy wire and the copper strip separately, and coat the copper strip on the surface of the aluminum-magnesium alloy wire by argon-arc welding method, then by drawing to make the surface of copper and aluminum-magnesium alloy wire can be well combined, so as to get the copper-clad aluminum-magnesium alloy wire with required specifications and performance.

Compared with copper-clad aluminum wire, copper-clad aluminum-magnesium alloy wire has the advantages of high strength. It overcomes the copper clad aluminum wires’ shortcomings of low strength and easy to break when the wire diameter is less than 0.5mm.

Using copper clad aluminum-magnesium alloy wire instead of pure copper wire braiding or as a conductor, can greatly save raw material costs.
We can provide copper-clad aluminum-magnesium alloy wire of various specifications, soft and hard state, with different copper volume ratios and conductivity.


Mainly used in coaxial cable braid layer, audio and video cable conductor and braid layer, etc.
