Anodizing is an electrochemical process that improves the durability of aluminum surfaces by forming a hard ceramic layer that is corrosion-resistant and UV-protective. The transparent oxide film retains its metallic appearance and can be dyed with a wide range of colors. This material can effectively enhance corrosion resistance and wear resistance. It can form colorful oxide films to increase the decoration, and the oxide films have hig...  more
