Anodic oxidation, the electrochemical oxidation of a metal or alloy. The process of forming a layer of oxide film on aluminum products (anodes) under the action of an applied electric current in the corresponding electrolyte and under specific process conditions for aluminum and its alloys.
In order to overcome the defects in the surface hardness and wear resistance of aluminum alloys, expand the application range and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloys, and anodic oxidation technology is the most widely used and successful one.
Cheetah Aluminum International Co., Ltd invests heavily each year in the development of aluminum profile anodizing to improve the decorative properties and qualified insulation of aluminum profiles. Provide a more beautiful surface and performance for aluminum window and door frames, industrial aluminum profiles. Better service for all distributors, wholesalers and retailers

|AA10||≥10µm||≥8µm||≥9||≥300g/µm||≤30mg/dm³||1, the surface of the aluminum profile is not allowed to have traces of being electrically burned, and the oxide film cannot fall off.
2, within 80mm from the end of the aluminum profile, it is allowed to have no local oxide film and electric burns.
