The anodizing process is intended to preserve the surfaces of aluminum parts for the long term and to make them appear more decorative. Thanks to this very hard and resistant oxide film, dirt can easily be removed from anodized components. It is impervious to scratches and easy to clean. Thicknesses of up to 30µm can be produced. The oxide film can be dyed using different processes. The dye is embedded in the film and thus protected against harmful environmental impacts.
