What are the surface treatment processes of aluminum alloy castings

The surface of aluminum alloy or zinc alloy die casting should be polished first, and then sandblasting, oil spraying, electroplating, paint baking, oil spraying and electrophoresis can be done

Anodizing can only be done with pure aluminum. General products are not anodized, because the color of silicon is not good-looking. But pure aluminum is difficult to die cast
