Anodizing

MIL-A-8625F Type II
Class 1 (Clear) or 2 (Color)

What is anodizing?

Brightly-colored metal pieces on a reflective surface.

Clear or color aluminum anodizing is an electrochemical process that produces a hard, clear oxide layer (< 0.0007″ thick) on the surface of the metal. This hard oxide layer is extremely porous. It looks like honeycomb or a metal sponge when viewed under a high-powered microscope.

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

Why anodize?

Because of its low cost, sulfuric anodizing is commonly specified for many engineered aluminum components requiring protection from minimum wear and corrosion. Sulfuric acid anodizing provides comparable corrosion resistance to chromic (Type I) acid anodizing, but it offers better wear characteristics.
