Aluminium finishing
Anodising
Anodising builds a hard, corrosion-resistant oxide layer that becomes part of the aluminium itself, so it won't chip or peel the way a plated or painted coating can. We offer two processes: hard anodising for wear-critical parts, and sulphuric anodising for corrosion protection and colour.

View processNot sure which you need? Hard anodising (25–70 microns) suits parts that see friction, pressure, or harsh environments; sulphuric anodising (5–25 microns) is the choice for general corrosion protection and colour. Send us the part and we'll advise.
