Aluminum Anodizing

Anodizing is one surface finishing treatment that allows the surface of Al to be electrochemically oxidized to generate a thick oxide layer. The oxide layer formed during conventional anodizing is usually optically transparent and contains a self-ordered, hexagonal, nano-porous structure. This structure is later sealed usually by hydrothermal treatments to transform the porous oxide to a dense hydroxide. The increased mechanical hardness of the surface due to the formation of anodic oxide improves the wear and scratch resistance.

In addition, corrosion resistance is enhanced due to the protective surface oxide layer. Anodizing of Al finds use as a pre-treatment process for paint systems for better adhesion too. We apply Aluminum Anodizing according to MIL standards and offer best quality with best delivery time.
