What are the advantages of anodizing aluminum alloy die castings?

　　The surface treatments commonly used for aluminum alloy die castings include spray painting, sandblasting, oxidation, etc. Different surface treatments can bring different performance advantages to products. So, what are the advantages of anodizing aluminum alloy die castings?

　　Due to the fact that anodizing can form an oxide film protective layer on the surface of aluminum alloy die castings, anodizing can increase the density and corrosion resistance of the die castings. Anodizing not only obtains a high transparency oxide film, but also can be dyed into various bright colors with fuel. Even with special treatment, it can achieve coating effects similar to ceramics.

　　Anodizing can greatly improve the wear resistance of die castings; Aluminum alloy die-casting parts have a high oxide film resistance and belong to the category of insulators, which can effectively serve as insulation; And after anodizing, it can still be further processed because the anodized film can serve as the bottom layer for other spraying methods, such as painting, electroplating, etc., which can increase adhesion.
