Anodising

Anodic oxidation is extensively used for the production of protective and decorative films on aluminium. In the anodising process the thin invisible film of aluminium oxide which forms naturally on the surface and provides some degree of corrosion protection for the underlying aluminium is increased to a considerably greater thickness, thus giving better corrosion protection. During the anodic oxidation process the surface of the aluminium is converted to aluminium oxide. The thickness of the oxide layer is approximately twice that of the aluminium removed. It is always useful to remember that if you require a material growth of 10um, then a 20um anodising thickness will be required. We can offer a selection of colours as well as natural anodising.
