JMA Aluminum profiles are corrosion-resistant metals. Because aluminum is very active, it is particularly easy to react chemically with air to form aluminum oxide. The aluminum oxide film is transparent and difficult to detect with the naked eye. This thin aluminum oxide film isolates the air and prevents the aluminum-based surface from being oxidized, so it plays an anti-corrosion role. However, due to the uneven hydrogenation film, the surface color of the aluminum alloy varies, and the naturally formed oxide film is very thin, easy to scratch, and has weak corrosion resistance. Therefore, the aluminum profile must be oxidized.

After anodizing, the surface of aluminum and aluminum alloys can obtain a dense film layer that is much thicker than the natural oxide film. After the artificial oxide film is sealed, the amorphous oxide film is transformed into a crystalline oxide film, and the pores are closed. Therefore, the gloss of the metal surface can remain unchanged for a long time, the corrosion resistance and mechanical strength are improved, and a decorative appearance can be obtained after dyeing. Since aluminum and aluminum alloy products have allowable characteristics after anodizing, aluminum anodizing technology is widely used in the surface treatment of aluminum products.
