Anodized aluminum plate is to form a layer of oxide film on the surface of the aluminum plate after corresponding treatment. According to the different process, it is divided into anodized aluminum plate and chemical aluminum oxide plate. Anodized aluminum plate is aluminum plate placed in the corresponding electrolyte as the anode, under specific conditions and external current action, electrolytic. The anodized aluminum plate forms a thin layer of alumina on the surface with a thickness of 5-20 microns, and the hard anodized film can reach 60-200 microns.

Chemical oxide plate is aluminum plate in weak alkaline or if acidic solution, part of the matrix metal reaction, the surface of the natural oxide film thickening or some other passivation film processing process, commonly used chemical oxide film chromic acid film and phosphoric acid film, they are thin and good adsorption, can be colored and sealed treatment.

Aluminum oxide plate has good processability, anodized alumina plate hardness is moderate, can be bent forming, can also carry out continuous high-speed stamping, very suitable for the processing of enterprise products, because the anodized aluminum plate decorative strong, enterprise products after production without surface processing, for enterprises, can greatly reduce the cost of production and production cycle.

At the same time, the aluminum oxide plate has a lasting weather resistance, the standard thickness of the anodized alumina version of the oxide film indoor use for a long time no discoloration, no corrosion, no oxidation, no rust, the thickened anodized alumina version of the oxide film can be applied to outdoor, can be exposed to the sun for a long time without discoloration.

Because of the beautiful appearance of the aluminum oxide plate, strong metal feeling, the surface hardness of the anodized aluminum plate is high, up to gem grade, good scratch resistance, no paint cover on the surface, retain the metal color of the aluminum plate, highlighting the modern metal feeling, improve the product grade and added value.
