The basic principle of copper aluminum casting is to pour molten metal into the mold and obtain the desired shape after cooling. Copper aluminum casting belongs to the field of metal processing, but it is different from metal smelting. Metal smelting is the process of extracting and refining ore into metal, while copper aluminum casting only involves melting the metal into the required components. The raw material for copper aluminum casting is metal ingots, not metal ores, so it is only a branch of the metal smelting industry.
Copper aluminum alloy has advantages such as good cutting performance, high hardness, good conductivity, good thermal conductivity, corrosion resistance, and lightweight. It is widely used in many fields such as automotive manufacturing, aerospace, mechanical processing, and electronic and electrical engineering. According to the different composition elements, aluminum copper alloys can be divided into two types: aluminum copper multielement alloys and aluminum copper binary alloys.
In the copper aluminum casting process, there are various processing techniques to choose from, including casting, cold working, hot working, welding, and surface treatment. Casting processes such as sand casting, low-pressure casting, high-pressure casting, and die casting are important methods for manufacturing copper aluminum alloy components and materials. In addition, cold and hot working techniques can also be used to manufacture various shapes of copper aluminum alloy components and materials, while welding technology can achieve the connection of copper aluminum alloys, manufacturing various shapes and sizes of components and components. Finally, surface treatment processes such as electroplating, spraying, anodizing, etc. can improve the corrosion resistance and aesthetics of copper aluminum alloys.
