Aluminium finishing
Hard anodising
Hard anodising builds a thick, dense oxide layer integral to the aluminium itself, giving high wear resistance, surface hardness, and corrosion protection for parts that see friction, pressure, or harsh environments. Wear resistance can approach that of hardened steel while keeping aluminium's light weight. We process to BS ISO 10074 and your own customer specifications.
- Thickness
- 25–70 microns
