Yes, die-cast aluminum can be anodized. However, compared with some other materials such as aluminum alloys, there will be some difficulties, but we can provide you with some suggestions!

Because the silicon content of die-cast aluminum anodization is relatively high, the uneven structure will affect the surface. For other alloying elements such as copper and iron, the oxide film will have color difference.

Advantages of die-cast aluminum anodization:

1. Improve corrosion resistance: It can improve the life of die-cast aluminum, and the anodized film on the surface can improve the corrosion resistance of high-pressure cast aluminum

2. Enhance hardness: The anodized aluminum film on the surface can enhance the hardness of the die-cast aluminum surface

3. Increase appearance: Anodizing can make the surface of die-cast aluminum beautiful

Disadvantages of die-cast aluminum anodization:

1. Relatively high cost: Compared with other processes, the cost of anodizing process is higher

2. The process is relatively complicated: The anodizing process of die-cast aluminum is relatively complicated and highly technical compared to other processes

3. Due to the high silicon content, the anodizing effect is not as good as other aluminum alloys

Total price:
Anodizing requires that there must be no impurities on the surface to ensure that the anodized film must be uniform and smooth. Excessive impurities and other components will affect the film thickness formed during anodizing, and even affect whether the film is formed. More importantly, when the anodized film is formed, other metal elements may directly change the color of the film, which is very unfavorable for dyeing after anodizing.

Aluminum or aluminum alloy die-castings generally contain a high amount of silicon. Even if HT412 die-cast aluminum special deashing agent is used, the anodized film may be dark, and it is difficult to obtain a colorless and transparent anodized film. As the silicon content increases, the color of the anodized film changes from light gray to dark gray, and then to black gray.

For aluminum alloy parts, anodizing and electroplating are not recommended. Because the surface of aluminum alloy die-castings is prone to gas marks, cold shuts, sand holes, etc., if anodizing is required, it is recommended to replace it with aluminum extruded profiles, and the electroplating material is recommended to be zinc-aluminum alloy or zinc alloy.Can die-cast aluminum be anodized?
