Although copper has very good thermal conductivity, aluminum is lighter and cheaper. Because the volume heat capacity of the material is much smaller than that of copper, when the same heat is obtained, the aluminum with the same volume will rise more. Because the heat dissipation bottleneck of metal heat dissipation devices lies in the low heat conduction efficiency of air. Higher fin temperature can obviously improve heat dissipation efficiency. Therefore, most of the heat sinks are made of aluminum. The Cu al bimetallic plate introduced by aluminum has high bonding strength due to the metallurgical bonding achieved by the new process. It can withstand stamping, extrusion and other processing without cracking. Due to the perfect combination of copper and aluminum materials, the thermal conductivity of the material itself is not affected. It can well combine the respective advantages of copper conductive aluminum powder as an ideal material for manufacturing high-performance electronic product radiators.

aluminum has developed a series of composite metal materials with advanced casting and rolling process as the core. Among them, Cu al bimetallic plate is the most widely used. Many aluminum copper connectors in the electromechanical industry, battery poles of new energy vehicles, and the use of copper aluminum composite to make transition plates instead of friction welding, ultrasonic welding and mechanical connection can greatly simplify the process and reduce the cost. Through dedicated research and development, our composites can achieve 100% metallurgical bonding, so as to obtain excellent copper aluminum interlayer conductivity and thermal conductivity. Compared with the cold rolling process, it also has better peel strength, stronger bending resistance and less electrode potential corrosion. In the field of Applied Materials in the future, it is bound to develop more application directions, create value for the society and obtain benefits for customers, which should shake the market ecology.

Application of Cu al bimetallic plate composite products: lithium battery pole material, copper aluminum composite plate (heat dissipation), cast rolling copper aluminum transition plate (energy storage battery), copper aluminum composite plate (power fittings), copper aluminum clad plate (LED substrate), copper aluminum composite plate, copper aluminum composite tape, etc.
