The anodization of industrial aluminum profiles is an electrolytic oxidation. The process of forming an oxide film on the anode of the aluminum profile is to increase the hardness of the aluminum profile, expand the use range of the aluminum profile, and increase the service life of the aluminum profile. In the process of anodizing, the color you want to make can be selected, such as black, silver white, red, purple and so on. These need to be made according to user needs. It can be seen from this point that the anodization of industrial aluminum profiles is actually decorative.
The true color oxidation of industrial aluminum profiles is actually the color of the finished product is the same as before, there is no difference. It is as if the color of the aluminum ingot is the color of the oxide film formed. Unlike anodizing, there are so many color options. Compared with the advantages of anodizing, such as the protection, decoration, and insulation, the natural oxidation may appear to be slightly inadequate.
