copper plated aluminum sheet

Jul 14, 2023

Although copper has very good thermal conductivity, aluminum is lighter and cheaper. And because the volumetric heat capacity of the material is much smaller than that of copper, the same volume of aluminum will heat up more when the same amount of heat is obtained. The heat dissipation bottleneck of the metal heat sink is that the heat conduction efficiency of the air is low. A higher heat sink temperature can obviously improve heat dissipation efficiency. Therefore, most of the heat sinks use aluminum. The copper plated aluminum sheet material introduced by Aluminum achieves metallurgical bonding due to the use of a new process, and the bonding strength is high. Can withstand processing such as stamping and extrusion without cracking. Due to the perfect combination of copper and aluminum materials, it does not affect the thermal conductivity of the material itself. It can be combined with the respective advantages of copper conductive aluminum diffusers, 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 technology as the core. Among them, copper plated aluminum sheet has the widest application range. There are many aluminum-copper connectors in the electromechanical industry and the battery poles of new energy vehicles. The use of copper-aluminum composite materials to make transition plates instead of friction welding, ultrasonic welding, mechanical connection and other methods can greatly simplify the process and reduce costs. After concentrating on research and development, our copper plated aluminum sheet can achieve 100% metallurgical bonding, so as to obtain excellent copper and 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, more application directions will be developed to create value for society and obtain benefits for customers, which should shake the market ecology.
