Anodize Type II (Sulfuric)
Sulfuric acid anodizing is a conversion on aluminum which changes the surface to an aluminum oxide film that can range from (.0001″) – (.001″) thick. This oxide coating gives the aluminum a greater resistance to abrasion, protects from corrosion, and provides excellent thermal and electrical insulation. The aluminum oxide builds up on the surface and penetrates into the material an equal amount. Sulfuric acid anodize films are naturally porous which makes them great for absorbing colored dyes which can be later sealed with a PTFE coating to further protect against abrasion and bleaching effects caused by sunlight.
