The melting points of aluminum and copper differ greatly, and aluminum is strongly oxidized at high temperatures. In addition, they can form intermetallic compounds such as AlCu2, Al2Cu3, AlCu and Al2Cu. Therefore, it is difficult to use fusion welding between copper and aluminum.
Since the plasticity of aluminum and copper itself is very good, their transition joints can be made by pressure welding. Henan Chalco adopts rolling and explosive welding to manufacture Al Cu bi-metal sheet plate busbar of various thickness ratios, and can be processed into plate-shaped, tubular and tube-shaped transition joints.
The Al Cu bi-metal sheet plate busbar produced by Henan Chalco, is widely used in various fields. In the electronic technology industry, in order to connect aluminum conductors and copper conductors, explosive welding is widely used. In the chemical industry, Al Cu bi-metal busbar are used instead of copper busbars to save copper; the biggest benefit of conductive busbar joints is the low contact resistance of copper and the low cost of aluminum.
The Al Cu bi-metal sheet plate is used as a transition joint after machining for the production line equipment for surface treatment of aluminum alloy profiles, as well as equipment for large-scale electroplating production.
