Aluminium finishing
Sulphuric Anodising
Sulphuric anodising forms a uniform, wear- and corrosion-resistant oxide layer united with the aluminium substrate. It provides an ideal base for colouring and, once sealed, an easy-to-maintain finish that is as much cosmetic as protective. We anodise aluminium and its alloys to AMS, MIL, and BS/ISO specifications as well as your own.
