In recent years, it can be said that aluminum alloy die-cast auto parts have become more and more popular. Among more models, aluminum alloy die-cast auto parts are very popular, so is it not easy to understand the surface processing technology of aluminum alloy die-cast auto parts? In fact, although aluminum alloy die-casting is relatively good in strength and toughness, it also has its own shortcomings, that is, relatively poor corrosion resistance, so it is usually used in combination with a protective layer and an anti-rust layer. , To ensure the service life. In fact, there are many surface treatments for aluminum alloy die-cast auto parts. Generally, a surface coating is selected, such as a chromate conversion coating. The coating of this material can effectively protect aluminum alloy die-cast auto parts from corrosion and conduction, and the effect is the same. Very good, and spr
