Type II class 1 is a non-dyed anodizing process. This process usually has a thinner coating with a tolerance ranging from 0.0002″-0.0005″.
Type II class 2 is a dyed anodizing process in which you can obtain a large variety of colors. This process has a thicker coating than Type II class 1, with a tolerance ranging from 0.0005″-0.001″.
Type III anodizing is also known as hard coat anodizing. Hard Coat anodizing is used in applications where the material needs to be corrosion, abrasion, and wear-resistant.
Type III class 1 is a non-dyed anodizing process. This process has a coating tolerance ranging from 0.001″-0.002″.
Type III class 2 is a dyed anodizing process in which black is used. This process has a coating tolerance ranging from 0.001″-0.002″.

We’ve helped companies just like yours with their Sulfuric Anodizing needs.
We take pride with what we do. That’s why we take care when anodizing your parts.
Base metals are washed with a commercial soap to clean away oils and other surface debris.
Base metal is submerged in a cold rinse tank where commercial soap and surface debris are washed away.
Base metal is submerged in a sodium hydroxide based etch that takes away surface imperfections, scratches, minor scuffs, etc. We have caustic or acid etching options as well.
Base metal is submerged in a sodium hydroxide based etch that takes away surface imperfections, scratches, minor scuffs, etc.
Deoxidizer is used to remove any film left from the etching process, leaving the metal brighter.
A cold rinse is used to remove leftover deoxidizer from the base metal to prepare it for the anodizing process. This is the final step in the cleaning process.
A controlled natural oxidation process using a sulfuric acid bath.
A three-step rinse process to clean and clear the sulfuric acid and remaining surface oxidation away.
Dye is added to a liquid bath where the anodized metal is then submerged to allow the dye to be absorbed. If clear, Skip to step 11.
Freshly dyed metal is rinsed to remove unabsorbed dye.
A sealant is applied to the anodized material to help corrosion resistance and dye retention.
