1. Product description
Due to the decreasing copper resources and rising copper prices, it is a general trend to develop new copper alloy materials. The price of aluminum is lower than that of copper, and aluminum resources are abundant in China. The high-performance copper clad aluminum plate is made by taking advantage of the metallurgical compatibility of copper and aluminum, controlling the initial temperature, roll gap spacing, rolling speed and other conditions to achieve a better metallurgical combination of copper and aluminum. The metallurgical properties of high-performance copper clad aluminum plate are similar to copper materials, which are characterized by strong conductivity, heat conductivity and corrosion resistance, and the preparation cost is greatly reduced, It can replace copper materials and be used in power system, machinery, automobile, daily necessities and other fields to achieve the goal of saving copper with aluminum.
2. Product Features
The basic theoretical research on the structural design of metal component layer, interface reaction control, heat treatment process, performance evaluation of composite plates, and the establishment of the relationship between the process performance, mechanical performance, thermal conductivity, corrosion performance, and the material structure, structure, and processing technology have become an important research and development direction of composite plates.
3. Application
The cooling fin materials are widely used in the market at present, including copper, aluminum and silver. Its thermal conductivity and heat dissipation capacity of bulk materials depend on the heat capacity of the materials. Copper has good thermal conductivity and poor heat dissipation performance, while aluminum has poor thermal conductivity and excellent heat dissipation performance. Silver combines the advantages of the two materials and has good thermal conductivity and heat dissipation performance. However, the heat dissipation performance of copper aluminum composite decreases with the increase of copper content, and its thermal conductivity increases with the increase of copper content. Therefore, a proper proportion of copper aluminum composite can achieve the balance of thermal conductivity and heat dissipation, and give full play to the thermal conductivity of copper and heat dissipation of aluminum. The comprehensive heat dissipation performance of copper aluminum composite fin is better than that of pure copper and pure aluminum materials, and it is a good heat dissipation material.
