Profile radiator introduction aluminum profile anodizing and natural color oxidation
The difference between anodizing and natural oxidation of aluminum profiles lies in the thickness and density of the oxide film. The thickness of the former oxide layer can be controlled, and the structure is dense, which better protects the internal material.
Anodizing of aluminum profiles is an electrolytic oxidation process in which an oxide film is formed on the anode of aluminum profiles. The purpose is to increase the hardness of aluminum profiles, expand the use range of aluminum profiles, and increase the service life of aluminum profiles. In the process of anodizing, the color you want to make can be selected, such as black, silver-white, red, purple, blue and so on. These need to be made according to the needs of the user. The anodization of aluminum profiles is actually decorative.
In fact, the natural color oxidation of industrial aluminum profiles means that the color of the finished product is the same as the previous one, and there is no difference. Just like what color the aluminum ingot is, what color is the formed oxide film. Unlike anodizing there are as many color options available. Compared with the protective, decorative, insulating and other advantages of anodizing, the natural color oxidation may be slightly insufficient.
