Sulfuric Acid Anodize

Tire Wheel Blue Black Metal 3D Rendering

Sulfuric acid anodizing is used on aluminum components for thermal and electrical insulation, to increase abrasion resistance, provide corrosion protection, and to add vivid color.

Sulfuric acid anodizing is a conversion process that takes between 20 to 60 minutes and changes the surface to an aluminum oxide film ranging from (.0001″) – (.001″) thick.
