Aluminum parts anodizing

Anodizing is an electrolytic anodizing process. In this process, the surface of aluminum and aluminum alloy is usually converted into an oxide film, which has protective, decorative and some other functional characteristics. From this definition, the anodization of aluminum includes only part of the process of generating anodized film.

 

Aluminum parts anodizing is widely used in mechanical parts, aircraft and auto parts, precision instruments and radio equipment, daily necessities and building decoration.Chalco can provide aluminum anodizing services according to customer needs

How CNC aluminum parts anodizing works?
 
Anodizing works by electrolytic passivation, a process where the part being coated serves as the anode of an electrolytic cell. When this cell is electrically charged with DC current, oxygen is created on the surface of the anode, which then reacts with the part to form an oxide layer. Anodizing is commonly performed in a sulfuric acid solution.
