The oxide film hardness of the Painting anodised aluminum sheet plate is second only to diamond, and it is a very hard compound with a micromolar hardness of 9 grades. The anodized aluminum plate is to place the aluminum plate in the corresponding electrolyte such as sulfuric acid, chromic acid, oxalic acid, etc. as the anode, and perform electrolysis under the action of specific conditions and applied current.
The Painting anodised aluminium sheet plate itself formed a thin oxide layer before being oxidized, but this oxide layer was not enough to protect the surface of the aluminum plate. After anodization, a thick oxide layer was formed on the surface Therefore, the surface of the Painting anodized aluminum sheet plate provides better scratch and abrasion resistance than the painted surface.
The surface hardness of the Painting anodized aluminium sheet plate is high, and scratch resistance and abrasion resistance are undoubted. It has obviously become a typical material that combines beautiful and practical use.
