What is alumina plate? Alumina plate refers to the aluminum plate formed by placing the aluminum plate in the corresponding electrolyte as an anode, and electrolyzing it under specific conditions and applied current. A thin aluminum oxide layer is formed on the surface of the anodized aluminum plate, the thickness of which is 5-20 microns, and the hard anodized film can reach 60-200 microns. The performance of the oxidized aluminum plate has been greatly improved, and the coloring effect is good, so it has become the preferred material for the shell of electronic products such as mobile phones and notebooks.

The anodized aluminum plate with standard thickness oxide film (3μm) is suitable for indoor use, and can maintain no discoloration, no corrosion, no oxidation and no rust for a long time. The anodized aluminum plate with thickened oxide film (10μm) is suitable for outdoor use and can be exposed to sunlight for a long time without discoloration. This kind of product can be stamped continuously at high speed, and can be directly processed into finished products without complex surface treatment, thus greatly shortening the production cycle and reducing production costs.

Alumina plate process:

Process flow of anodized aluminum plate: put on the shelf, degrease~wash~alkali etching,wash,neutralize,wash,anodize,wash, seal holes,wash,shelf,test,pack. Degreasing, alkali etching, neutralization, anodizing, sealing and other processes in the process flow are the key to ensure the quality of oxidation treatment.

The main products of aluminum plates for oxidation are 1 series, 3 series, 5 series and 6 series products, and the main alloy grades are 1050, 1060, 1070, 1100, 3003, 3004, 3005, 5005, 5052, 5083, 5086, 5182, etc. Alumina plates are widely used in rail transit, electronic appliances, construction and engineering, molds and other fields.
