At present, the substitution of aluminum for copper in the power system is increasing. At present, the state has launched the national standard of copper-clad aluminum cable. In terms of equipment, there are poor contact, heating, sparks and increased resistance at the contact between copper and aluminum due to corrosion, resulting in equipment accidents and increased maintenance costs. If Cu al bimetal sheet is used at the joint, these problems can be effectively solved. At present, the Cu al bimetal sheet commonly used in the market is mostly flash welded products. However, due to the complex flash welding process and the need for large equipment, the product cost is high and the application range is narrow. Based on this situation, aluminum has successfully developed Cu al bimetal sheet and copper aluminum composite connector by referring to domestic advanced experience and adopting advanced copper aluminum molecular fusion binding technology. The molecular fusion of the two materials at the contact surface is carried out by pure physical process.

The copper aluminum composite produced by pure physical process is a kind of conductive material with stable performance, high conductivity, not easy to fracture, not easy to layer, low resistance, strong oxidation resistance, electric corrosion resistance, easy molding and processing and stable output performance. It is not affected by the use environment, the composite surface will not fracture, but it can achieve excellent conductivity without reinforcement measures

aluminum's Cu al bimetal sheet is widely used in high and low voltage electrical appliances, electronic components, high and low voltage power transmission and transformation accessories, electrical accessories, power fittings and other industries, as well as traditional copper plate decoration industries such as copper door, copper mural, copper technology, copper decorative plate and copper ceiling. It has been tested, inspected, installed and used by many listed enterprises and national key projects, It has been affirmed by our customers.

The Cu al bimetal sheet manufactured by aluminum physical and molecular fusion process is cold punched at room temperature. The composite has excellent extensibility, and there are no cracks, folds, peeling, delamination and falling off at copper, aluminum and their composite interfaces. Especially for the power fittings industry, it is used for the production of copper aluminum composite and copper aluminum transition equipment clamps. Fast forming, reliable electrical performance, strong oxidation resistance, electrical corrosion resistance and chemical reaction resistance.

It can also match the material thickness according to customer needs, which can ensure the processing of cold stamping, 90 ° bending, U-bend, square hole, round hole and special-shaped hole.
