MIL-A-8625

Class I - Sulfuric Acid (Clear)
Sulfuric acid anodizing produdes an oxide coating on aluminum alloys that increases corrosion resistance and may also be used as a base for paint coatings. Other uses are for limited abrasion resistance, electrical insulation and for decorative purposes. Conventional sulfuric acid anodizing is most useful making aluminum parts more attractive and more corrosion resistant. The natural appearance of the aluminum oxide film is near transparent, and left as-is, it is known as clear anodizing. This is the most economical form of anodizing. The typical thickness ranges from .3 to .7 mils.
