6061 aluminum profile is one of the most widely used and economical metal materials. Whether in construction and automotive manufacturing or aerospace, aviation and marine applications are very extensive. Especially after the anodization of the 6061 aluminum profile, its application is very extensive, and more people like it.
Since aluminum and aluminum alloys will oxidize in the air, it will lose the original luster of the aluminum metal surface, and the oxide film naturally formed on the aluminum surface is amorphous, although this natural oxide film will slightly aluminate the aluminum surface. Passivated, but it is very thin, due to large porosity and poor mechanical properties. Therefore, it cannot effectively prevent the corrosion of aluminum metal by various media in the atmosphere.
The 6061 anodized aluminum alloy profile can improve various properties of the aluminum alloy, and the anodizing method can obtain a dense film layer which is much thicker than the natural oxide film. This artificial oxide film is then sealed, its amorphous oxide film is transformed into a crystalline oxide film, and the pores are also closed, so that the surface gloss of the metal can be kept longer, and the corrosion resistance of the metal And the mechanical strength will increase accordingly, and then the metal can be dyed to obtain a better decorative appearance.


There is also the 6061 anodized aluminum alloy profile which can prevent the corrosion of the product very well: this is because the film obtained by anodizing aluminum and aluminum alloy is properly sealed and has good stability in the atmosphere. Whether it is sulfuric acid solution, oxalic acid solution or chromic acid solution, the oxide film obtained in the normal process, the corrosion resistance of the metal will be stronger with its anodization.
Furthermore, the 6061 anodized aluminum alloy profile is also very aesthetically pleasing in appearance, because when the aluminum and the aluminum alloy are anodized, a highly transparent oxide film is obtained, which can adsorb various organic dyes or inorganic substances. pigment. Some add some new technology, one oxidation multiple coloring, fireworks pattern, wood grain pattern, oxidative offset transfer printing, porcelain oxidation, etc., which will make the appearance of aluminum products more beautiful, and can better satisfy customers. Appearance requirements. Its color film is both a decorative layer and an anti-corrosion layer. The lighter and gold pen that we often touch are all such anodized film.
The wear resistance of 6061 anodized aluminum alloy profiles is also extremely high. Both sulfuric acid and oxalic acid solutions can be obtained through the anodizing process conditions to obtain a thick and hard film layer, which can be selected by using the pores and absorption properties of the film layer. The oil can be used more effectively in the working condition under friction. It also has the characteristics of lubrication and wear resistance. We have seen that the engine cylinders and pistons of automobiles and tractors are all anodized.
