Chromic Anodising produces a stable oxide layer on the surface of aluminium materials. The process involves submerging the component in a chromic acid solution, whilst applying a voltage across the component and the solution.


Chromic Anodising isn’t the most commonly available form of anodising due to it’s limited applications and environmental impacts.


Oxide layers produced are the thinnest of the Anodising processes, being around 5 Microns. This limited thickness also prevents the ability of the oxide layer to be coloured or dyed with consistency and colour depth.
