Hard Anodising

Hard Anodising is an electrolytic process used to increase the thickness of the natural oxide film on the surface of Aluminium and its Alloys and produces a very hard corrosion resistant insulated surface.

Anodising thicknesses can range from 25 microns to 75 microns depending on the Alloy being processed.

The colour can vary from light to dark grey depending on thickness with the option of being dyed black, other colours can be made available upon request. We can mask off areas where Anodising is not required.

A secure contact point is required due to the current needed to produce the Hard Anodised coating.
