What is an anodized aluminum sheet?

The surface treatment technology of anodized aluminum plate is different from ordinary painting technology. It passes through the current to make the conductive acid electrolyte electrolytic, so that the aluminum metal surface of the anode is oxidized, and a thick and fine protective film of alumina is naturally grown on the aluminum surface. This layer of oxide film is not an additional layer and will not fall off.

Anodizing aluminum plate, mainly aluminum anodizing, is the use of electrochemical principle, material in electrolyte solution, the surface of aluminum plate to generate a layer of dense oxide film process, called surface anodizing.

Anodized aluminum plate process

Anodic oxidation can improve the corrosion resistance, surface hardness and wear resistance of aluminum alloy products, and has a good decoration after coloring treatment.

The process flow of anodized aluminum plate is mainly from degreasing → corrosion washing → neutralization → anodizing → coloring → hole sealing.
