Anodizing, Sulfuric Acid

Bright dip, clear and colored finishes

Mil-A-8625 Type II, Classes 1 & 2 and AMS 2471

The thickness of this anodize process is normally between 0.0001" and 0.0006" thick. The build-up is 1/2 of the total thickness since 1/2 of the anodizing layer penetrates the base metal. The aluminum oxide makes the surface of the aluminum harder and it keeps the black oxide from rubbing off the aluminum, but the corrosion protection comes from the sealer after the anodizing by placing metal salts in the pores of the oxide.

The coating can be dyed colors using organic dyes; however, these colors will eventually fade in direct sunlight.

Frequently Asked Questions

Why did my black fade to purple in a few weeks? The quality of the dye used and the quality of the sealer after the dye will keep the colors from fading. We only use the highest quality dyes and we seal all our parts with a hot nickel acetate solution for the highest quality colors.

Why are some of my parts different colors after a clear anodizing? Different alloys of aluminum will anodize a slightly different color, so the end product will also look different even if the part is dyed. To keep the colors the same, use consistant lots of aluminum alloys.

How far will the anodizing go into a hole? A general rule of thumb is that the anodizing will stay a consistant thickness into a hole, the distance of the hole diameter. The anodizing will then begin to get thinner as the hole goes back further.
