What is the color of aluminum after anodizing

white

The principle of anodic oxidation of aluminum is essentially the principle of hydrolysis. At the cathode, hydrogen is released by the following reaction: two hydrogen ions combine with two electrons.

At the anode, four hydroxide ions combine with four electrons, resulting in not only molecular oxygen, but also atomic oxygen (O), and negatively charged oxygen ions, usually represented as molecular oxygen in the reaction.

After anodic oxidation treatment, aluminum surface can form several microns to several hundred microns of oxide film. Compared with the natural oxide film of aluminum alloy, its corrosion resistance, wear resistance and decoration are obviously improved and improved.
