The 5083 aluminum bar is obtained through extrusion process. The surface of the extrusion molding 5083 aluminum bar may not have strong corrosion resistance, so anodizing is needed at this time. Next, the 5083 aluminum bar manufacturer will introduce to you the anodizing process of 5083 aluminum bar.
1. Surface pretreatment: clean the surface of 5083 aluminum bar so as to facilitate completely compact oxide film.Mirror or matte surfaces can also be obtained at the same time by various mechanical techniques.
2. Anodic oxidation: After surface pretreatment, an oxidation film will be formed on the surface of 5083 aluminum bar, forming a compact, porous and strong adsorption AL203 film.
3. Hole sealing: The pore and pore structure of the porous oxide film is closed, which continuously enhances the anti-pollution, anti-corrosion and anti-wear properties of the oxide film.The oxide film is colorless and transparent.By using the strong adsorption property of oxide film before sealing the hole, some metal salts can be adsorbed and deposited in the hole, making the appearance of 5083 aluminum bar appear many colors instead of the original colors, such as black, bronze, etc.
The anodic oxidation process of 5083 aluminum bar is introduced here. If you want to consult the price of 5083 aluminum bar, please contact us.
