In the metals, aluminum is more active metal, it is easy to react chemically with the outside world Acid substance, if they are being in the water for long time, aluminum molecules will react in water. So for high-strength aluminum alloy 6061-T6, or 6082-T6 aluminum alloy welded truss, how can we do to better maintaining the stability of these products? That is --- surface treatment technology, which we all know in this industry. Surface treatment technology aimed at enhancing the stability of aluminum product by enhancing the ability of anti-acid, oxidation treatment. It will be with an oxide film surface, thereby preventing aluminum alloy surface contact with external substances and chemical reaction occurs, leading to corrosion of aluminum truss.

This technology is by overcoming the aluminum a hardness and abrasion defect, to extend the period of use of aluminum products. Thus, surface treatment technology has become an important maintenance process. We have always been being the trust of our customers in this technology.

Anodic oxidation film of aluminum or alloy is formed on the surface of the aluminum oxide thin layer and the thickness is 5 to 20 microns.

The metal oxide film will change the surface state and properties, such as surface shading, improve corrosion resistance, improved abrasion resistance and hardness, protect the metal surface. Such as aluminum anodized, the aluminum as an anode in the appropriate electrolyte solution (such as sulfuric acid, chromic acid, oxalic acid, etc.) and impressed current, will happen electrolysis under certain conditions. Anodized aluminum or an alloy can improve the hardness and wear resistance.
