MIL-A-8625F  Type II, Class 1 or 2

Clear or color aluminum anodizing (also known as sulfuric acid anodizing) is an electrochemical process that produces a clear oxide layer, usually less than 0.0010″ thick, on the surface of the metal. This oxide layer is extremely porous and hard. The pore structure, when viewed under a high-powered microscope, looks like a honeycomb or metal sponge.

When colored, dye or ink is deposited into the pore structure and sealed. Sealing improves corrosion protection, locks the color in and stabilizes the surface.

Sulfuric acid anodizing provides comparable corrosion resistance and better wear characteristics than chromic (Type I) acid anodizing.

Because of its low cost, sulfuric anodizing is commonly used on many engineered aluminum components requiring protection from minimum wear and corrosion.

AMF has a variety of anodize colors to choose from.  Please contact our Sales Department for more information.
