How is Colored Aluminum Processed ?

Colored aluminum plate is made by surface treatment of aluminum plate, and commonly used surface treatment methods include oxidation, spraying, anodizing, etc.

1. Oxidation method: Surface oxidation method utilizes the oxidation properties of aluminum metal to create an oxide layer on the surface of aluminum, and then uses various colored oxidants for dyeing. This method can produce aluminum plates with different colors, but the color is relatively single and the weather resistance is average.

2. Spraying method: Surface spraying method is to spray paint on aluminum plates, and through drying, curing, baking and other processes, it solidifies to form rich colors and textures. This method can produce aluminum plates of various colors and textures, but the weather resistance is average.

3. Anodizing method: Colored aluminum plates with excellent weather resistance and good decorative effects can be made using anodizing method. This method utilizes the electrolytic action of aluminum alloy in the electrolyte to form a controllable thickness oxide layer on the surface, which is then colored. Colorants can further alter the color and texture of aluminum panels, providing rich color and decorative effects.

Overall, there are three main methods for processing colored aluminum plates, each with its own advantages, disadvantages, and applicable scenarios. When selecting colored aluminum panels, factors such as color, weather resistance, and decorative effects need to be considered according to actual needs.
