anodised aluminium angle trim

Oxidation coloring is a commonly used surface treatment process for aluminium angle trim. Its function is mainly to enhance the corrosion resistance of the product surface and make the aluminum alloy decorative strips have a decorative effect. The oxidation coloring effect is related to the material composition and process parameters of aluminum alloy.

Anodised aluminium angle trim commonly has the following oxidation coloring treatment methods:
1. Colored anodic oxide film Aluminum anodic oxide film is colored by adsorption of dyes.
2. Spontaneous color anodic oxide film This anodic oxide film is a kind of colored anodic oxide film spontaneously generated from the alloy itself under the electrolysis of a certain specific aluminum material in a suitable electrolyte.
3. The electrolytic coloring of the anodic oxide film is colored by metal or metal oxide electrodeposition through the gaps of the oxide film.
The above is the coloring process of anodised aluminium angle trim, welcome to consult and exchange
