Hard Anodizing (Type III) Overview
Hard anodizing (Type III) is an electrochemical process that forms a thick oxide layer on aluminum. Its typical thickness of 35–50 μm provides higher wear and corrosion resistance and greater surface hardness.
- Wear resistance:
The thick, hard oxide layer improves resistance to wear.
- Corrosion resistance:
The anodic coating helps protect aluminum parts against corrosion.
- Electrical insulation:
The anodized coating reduces electrical conductivity.
- Appearance:
Clear and black finishes provide different visual options.
Hard Anodizing (Type III) Specifications
| Color | Visual Appearance | Typical Thickness |
|---|---|---|
| Clear | Clear, non-conductive hard anodized finish | 35–50 μm |
| Black | Deep, consistent black finish | 35–50 μm |
