Aluminum anodizing is the electrochemical oxidation of the surface of aluminum to produce a more stable oxide on its surface.  This is done to increase corrosion resistances and durabilities.  It also is done to obtain electrical resistant surfaces, to beautify and add color, and/or add lubrication qualities to a part.  There are many different types of anodizing electrolytes used from sulfuric acid, chromic acid to boric acid electrolytes.

A large majority of parts processed by Coating Technology are done in sulfuric acid anodize per MIL-A-8625F Type II and chromic acid anodize per MIL-A-8625F Type I and IB.  Parts anodized will exhibit porous oxide cells which then can be dyed or impregnated with lubricants then sealed to specifications.

The available processes are:

Mil-A-8625F Type 2 Sulfuric Acid Anodize
Mil-A-8625 Type I and IB Chromic Acid Anodize
