Anodizing aluminum means mill finish aluminum with the anodizing process, it is a high value-added product and the processes in the production will be more, the anodizing color can be Matt silver, anodized champagne, anodized bronze, anodized black, anodized gold and some other colors.
It is the mill-finished aluminum next surface treatment product, the anodizing production will be done in the tanks for the anodizing film, which can increase the thickness of the oxide coating on the aluminum improving its resistance to abrasion.
The anodizing processes can be alkali etching and acid etching; also some extruders make the polishing, sandblasting or shot blasting operation on the aluminum profile before anodizing to remove the die line and scratch.
The anodizing aluminum surface will be smooth and elegant and it is widely used in windows and doors, curtain walls, industrial aluminum profiles, and decoration profiles.
