In contrast to the conventional galvanising process, no foreign metallic cover layer is applied during anodising. Instead, the surface of a light metal component is converted into an oxide layer by the galvanising/anodising process.
Since the oxide layer develops from the base material, the dimensional increase is only 50-55%. The remainder grows into the base material, which results in good adhesion to the base. Collini anodises aluminium (also known as Eloxal) and titanium. The anodising layers are hard, corrosion and wear resistant, and they have a good electrical and thermal insulating effect. Special anodising methods are offered for tribological systems.
Fields of application include all areas in which aluminium with increased technical specifications is required. For components made of titanium, there is an option for bio-compatible colour coding, which is particularly relevant for use in medical technology.
