The anodic layer can be divided into two categories:

Porous Layer Anodizing — In sulfuric acid, oxalic acid and others formed a layer of very fine pores perpendicular to the surface;
Barrier Layer Anodizing — A nonporous, extremely thin layer formed in an electrolytic bath of ammonium borate and other neutral salts, which is commonly used in electrolytic capacitors, etc.

At present, the application of single anodized aluminum alloy building profiles in practice has been significantly reduced. The electrolytic coloring anodic coating, the organic coloring anodic coating, the porcelain anodic oxidation, the hard anodic oxidation coating, and the imitation stainless steel oxidation coating are widely used. Generally speaking, the factors that affect the aluminum alloy coloring are as follows:
