Hard Anodize

Hard Anodize color will vary from light tan to black depending on alloy and thickness. The Hard anodized coating can be dyed in darker colors depending on thickness. Hard anodize coating penetrates the base metal to a depth equal to the build up on the surface. The thickness measurement includes both the buildup and penetration. This process provides a very hard ceramic type coating and good dielectric properties. Abrasion resistance will vary with the thickness of coating. Where extreme abrasion resistance is required, parts should not be sealed, as some softening will occur. Hard anodize corrosion resistance is good. Where increased corrosion resistance is required, parts should be sealed in a dichromate solution.
