Surface treatment of aluminum – oxidation and anodizing
Aluminum oxide (coloring) Aluminum and aluminum alloys are more and more widely used because they are easy to form and lighter than other metal materials. The chemical properties of aluminum and aluminum alloy are very active, so certain protective treatment must be carried out: such as electroplating, spraying, organic protection and oxidation treatment. Oxidation treatment […]
