Short answer: Anodizing grows a controlled aluminum-oxide layer for corrosion resistance, hardness and color – Type II for decoration and Type III for hard wear – with the comparison in our Anodizing vs Powder Coating guide and arranged via our Metal Coating Supplier page.

What Anodizing Does
An electrolytic process thickens the natural oxide on aluminum into a sealed, integral layer, with the material basis in our Aluminum Supplier page and the finishing overview in our Metal Surface Treatment Guide.
Type I, II and III
Type I chromic anodize is thin and used as a primer, Type II (5 to 25 microns) is the decorative color workhorse, and Type III hardcoat (25 to 100 microns) resists wear, with the comparison in our Anodizing vs Powder Coating guide.
| Type | Thickness | Use |
|---|---|---|
| Type I | Thin | Chromic, primer |
| Type II | 5 to 25 um | Color, decor |
| Type III | 25 to 100 um | Hard, wear |
Color and Sealing
Type II takes dyes before sealing for stable color; specify shade, thickness and seal type.
Best Applications
