Die casting of auto parts has a wide range of applications, and its plasticity can be made into various shapes, and there are many applications in auto parts. Today I will tell you what its processing technology is. 1. The higher the purity of Lehe chrysanthemum, the better the corrosion resistance. As we all know, pure aluminum reacts with oxygen in the air to form a very thin and dense natural oxide film on the aluminum surface. Its speed is faster and thicker than other metal oxide films. It can prevent the corrosion of harmful gases and moisture in the air. Protective effects. 2. Although pure aluminum has good corrosion resistance, its mechanical strength is poor, which limits the application of aluminum to a certain extent. Adding appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types of aluminum greatly expands the scope of application. Although aluminum alloy has high mechanical strength, its corrosion resistance is not as good as pure aluminum and may be oxidized and corroded. This requires powder coating to protect the aluminum alloy profile. Therefore, in the aluminum alloy processing process, the surface treatment of the aluminum material. Aluminum profile has the advantages of high corrosion resistance, various colors, and good surface texture.
