Die cast aluminum is also a common aluminum alloy raw material for us. Usually, semi formed items are made through forging process, and of course, the silicon content is usually 12%. To reinforce the hardness of the workpiece. In terms of design and surface treatment, anodizing is usually carried out. When we talk about die-cast aluminum anodizing, the natural color refers to dark gray. Of course, there are also small amounts of die-cast aluminum that do not contain silicon and are pure cast aluminum. For example, common die-cast aluminum molding items such as door handles may have any desired decorative anodizing effect. What we are focusing on today is the natural color anodizing of die-casting aluminum (containing silicon). So what are the factors that affect the coloring effect of die-casting aluminum? Let's take a brief look below:

Simplify the anodizing process of die-casting aluminum, eliminate unnecessary pre-treatment, and address color depth issues;

B reduces the concentration of the electrolyte in the anodizing tank, which is environmentally friendly and meets the process requirements, and deals with color depth issues;

C Reduce the transmission voltage value of anodic oxidation, which not only saves energy but also conforms to the electric polarization process, and deals with the problem of color depth;

The temperature of the D constant temperature anodizing bath solution should not exceed 30 ℃ to address color errors.

The above are the factors that affect the coloring effect of die-casting aluminum, hoping to be helpful to you.
