The role of aluminum surface oxidation treatment has those

Aluminum parts usually need to be oxidized before being sold on the market, so what properties does aluminum oxidation bring to aluminum parts? What are the effects of aluminum surface oxidation treatment?

1. The cleaning of the surface of aluminum parts can be used to treat the corrosion layer of aluminum alloy profiles, the residual salt and oxide layer on the surface of heat treatment process parts, the oxide layer on the surface of forged parts and weldparts, the sand and oxide layer on the surface of cast parts, the residual dirt and fine burr on the surface of machined parts, and the surface of old parts to remove the surface adhesion layer and show the natural color of the substrate. The surface cleaning quality can reach Sa3 level.

2, aluminum parts before the surface coating pretreatment can be used for all kinds of plating process, coating process and bonding process of the pre-treatment process, improve the adhesion between the coating, coating and bonding parts.

3. Adjusting the physical and mechanical properties of aluminum parts can adjust the surface stress state of aluminum parts, improve the lubrication conditions of coordinated parts, and reduce the noise in the operation stage of parts. It can cure the surface of aluminum parts and improve the wear resistance and fatigue strength of parts.

4, aluminum parts surface finishing processing can adjust the surface roughness Ra value of aluminum parts. Matte or diffuse reflective surfaces can be formed to achieve the effect of finishing aluminum parts.
