Introduction to the advantages of Copper- Aluminum Composites busbar

Copper-Aluminum Bimetal Composites Busbar, As a kind of high-tech energy-saving conductor material, the Copper-Aluminum Composites busbar has both the conductivity of copper and the low density of aluminum.

The application of the Copper-Aluminum Composites busbars can be traced back to the 1960s. With the development of the economy, some countries in Europe and the United States began to study and apply Copper-Aluminum Composites materials and formulated conductor standards for the application of this material. Copper-Aluminum Composites is considered to be the third generation of new conductors after copper and aluminum in Europe and the United States. Basically, every country has relevant industry standards. It has now entered the practical stage and is widely used in new energy vehicles, automation, metallurgy, high and low-voltage Electrical appliances, construction, and other industries.

Comparing with copper busbars, the advantages of the Copper-Aluminum Composites busbars as below.

Good conductivity

The Copper-Aluminum Composites busbars with a volume ratio of 15% or 20% of copper and aluminum can conduct electricity, and its AC current carrying capacity is 85% of that of pure copper.

Light weight

the density of Copper-Aluminum Composites busbar is only 37%-40% of pure copper busbar, and the length (volume) of the same weight is 2-2.5 times of that of pure copper busbar.

Good mechanical properties

Good tensile strength, flexibility and elongation.

Promote The Strong Combination Of Copper and Aluminum

Promote the strong combination of copper and aluminum: at different ambient temperatures, atomic particle bonding is realized between two different metal materials, and the copper layer (tin and zinc layer) is evenly distributed without any physical defects.

Good Ductility & Reliability

After a special heat treatment process, it has a certain plasticity, which is conducive to punching, shearing, bending and processing products without cracking and separation. In order to improve the corrosion resistance of the material, tin plating and galvanizing treatment can be performed on the surface of the copper layer.

Cost Down Much

Less copper materials, greatly reduce the cost of production support, green and environmental protection, without any pollution.
