Anodizing is one of the best methods for surface treatment of aluminum alloy shells. It has an irreplaceable advantage. Even if other treatments are required, such as coating organic film layers, anodizing is generally performed first to improve the film adhesion. The anodizing process relies on its technological advantages:

1. Strong metal feeling: The surface of the anodized aluminum plate has high hardness, gem-quality, good scratch resistance, no paint coverage on the surface, retaining the metallic color of the aluminum plate, highlighting the modern metallic feeling, improving the grade and added value of the product.

2. Strong anti-fouling: no fingerprints, no stains, easy to clean, no corrosion spots.



Because of the above advantages, the anodizing process has been favored by high-end consumer electronics manufacturers.

It is easy to sweat in summer, and the sweat is very corrosive. After a summer use, the surface coating of many mobile phone handsets will fall off a lot. If the sweat enters the inside of the mobile phone, it will corrode the earpiece and lead to replacement of the accessories.

The anodizing process has excellent corrosion resistance. Combined with excellent process parameters, the surface effect and color of aluminum can still be guaranteed after 4000 hours under the artificial salt spray test. The anodized film forming process is grown from the surface of the aluminum alloy substrate，so the bonding is quite good and does not fall off. The anodized layer acts as an insulating ceramic layer, and because of its non-conductive nature, even if it is contaminated with sweat, There will not be a lot of corrosion like a coating.
