What Are The Advantages Of Anodizing On Aluminum?

1. Prevent corrosion of aluminum products

Since the film layer obtained by anodization itself has sufficient stability in the atmosphere, the oxide film on the aluminum surface can be used as a protective layer.

2. Protective and decorative products

For most aluminum and its alloy products that require surface finishing, after chemical or electrochemical polishing, anodizing with the sulfuric acid solution can obtain oxide films with higher transparency. This oxide film can adsorb many kinds of organic dyes and inorganic dyes, so it has various bright colors. This color film is both an anti-corrosion layer and a decorative layer. Under some special process conditions, a protective and decorative oxide film similar in appearance to porcelain can also be obtained.

3. Improve the insulation of aluminum products

The oxide film obtained by anodizing aluminum and aluminum alloy products has a large resistance, so it has a certain effect on improving the electrical insulation of some products. And after processing, the bonding force with the organic coating and the bonding force with the inorganic coating layer is also improved.
