Why Does Aluminum Need Anodizing?

- May 11, 2018 -

Q: What does anodizing mean and why does most of the aluminum have this surface treatment? 

Does it can gain high corrosion resistance when using anodizing or it won't rust if the aluminum has this kind of surface treatment since aluminum oxidizes on the surface and has the ability to resist corrosion. 

A: Aluminum itself will have surface oxidation, but the oxidation isn't beautiful. 

Anodizing is the use of aluminum products as the anode into the liquid with a direct current, using chemical medicine to form a very fine and uniform holes in the surface of aluminum. Then color on the surface or make a mirror effect. 

Anodization is to enhance decorative and increase adhesion in order to prevent the color from fading. The anodized aluminum can be marked by laser marking machine clearly.
