Anodizing of aluminum profiles can be applied to daily life. Due to the characteristics of this process, a hard protective layer is formed on the surface of the aluminum, which can be used to produce daily necessities such as kitchenware. However, the actual anodizing effect of aluminum castings is not very good. The surface is uneven and only blackish gray. Aluminum profiles are stronger. The following is a brief and detailed introduction to the solutions for the oxidation of aluminum plates.

Aluminum plate oxidation solution: Aluminum plate oxidation method

 

In the past decade, the technology of aluminum oxidation coloring in our country has made rapid progress. Many processing plants have adopted new technological processes and accumulated sufficient experience in actual production. The anodizing process of aluminum and aluminum alloys has been perfected and developed, and the appropriate process can be selected according to the specific production requirements. Before choosing the oxidation process, it is recommended to have a good understanding of the material condition of aluminum or aluminum alloy profiles. Because the quality of raw materials and the differences in their components will immediately affect the quality of aluminum after anodizing. For instance, if the aluminum surface has defects such as bubbles, scratches, peeling, and roughness, most of these defects will still occur after anodizing. The alloy composition also simultaneously affects the surface appearance after anodizing. For instance, aluminum alloy profiles containing 1 to 2% manganese appear dark brownish blue after oxidation, and the surface tone changes from dark brownish blue to dark coffee color after oxidation. Aluminum alloy profiles containing 0.6 to 1.5% silicon appear dark gray after oxidation, and white gray when containing 3 to 6% silicon. Iron content presents a milky color, magnesium content an orange-yellow to dark gray color, and nickel content a light yellow color.

 

Generally speaking, only aluminum with magnesium and titanium content exceeding 5% can obtain a colorless, fully transparent, bright and clean appearance after oxidation. After selecting aluminum and aluminum alloy materials, aluminum plate manufacturers, of course, need to consider choosing the appropriate anodizing process.
