Copper Clad Aluminum

Copper-clad aluminum wire refers to the aluminum core wire as the main body, coated with a certain proportion of copper layer on the outside of the wire, can be used as a conductor for coaxial cable and electrical equipment wire and cable conductor. The specific gravity of aluminum wire is small, but its welding performance is not good, so in the aluminum wire outsourcing copper layer, this copper-clad aluminum wire can take advantage of the advantages of small specific gravity of aluminum, but also improve the welding performance.

According to mechanical properties, it is divided into soft state (A) and hard state (H), and copper-clad aluminum wire is divided into two kinds according to the volume ratio of copper layer (10%, 15%,20%).

Copper clad aluminum wire has the characteristics of small proportion, low transportation cost, low price, good weldability and so on.

Copper clad aluminum wire can be processed and derived from a variety of cables, such as power cables, communication cables, control cables, special cables, these cables are widely used in power, railway, communications, aviation, medical, transportation, construction, ships and other industries.

In terms of physical properties, copper-clad aluminum wire has good low density, large specific heat and small specific gravity.

Quality and control standards meet ASTM B566, British standard (BS4990-73), Japanese standard (JCS 340A-1992), GB /T 29197, SJ/T11223, SJ/T11472, etc.
