Anodic oxidation is the electrochemical oxidation process of metals or alloys. The process in which aluminum and its alloys form an oxide film on aluminum products (anodes) under the action of an external current under corresponding electrolytes and specific process conditions. Anodizing usually refers to sulfuric acid anodizing, which utilizes electrochemical principles to generate a layer of Al2O3 (aluminum oxide) film on the surface of aluminum and aluminum alloys.

Advantages of anodizing
The main features of anodized aluminum include increased hardness, increased wear resistance, excellent corrosion resistance, good heat resistance and insulation, and can be presented in a variety of colors.
Improve hardness and wear resistance:
a layer of dense alumina film is formed on the surface of anodized aluminum oxide, which can significantly improve the hardness and wear resistance of the material. The hardness can reach 200 to 500HV, making the anodized aluminum perform well in the face of scratches and wear 1.
Excellent corrosion resistance:
the surface oxide film of anodized aluminum can effectively prevent direct contact between aluminum and air, thus resisting corrosion. This corrosion resistance enables anodized aluminum to be used in harsh environments for a long time without corrosion or oxidation
Good heat resistance and insulation:
the anodized aluminum plate has good heat resistance, and the melting point of the hard anodized film is up to 2320K. At the same time, it also has excellent insulation and breakdown resistance of up to 2000V, which makes anodized aluminum perform well in high temperature environments or electrical applications
Can show a variety of colors:
During the surface treatment of anodized aluminum oxide, electrolytic coloring technology can be used to make the material show a variety of colors and luster, which increases its decorative and aesthetic
