Sulfuric Anodizing


Type II Anodizing, also known as regular or sulfuric anodizing, is the process of using electrolytic oxidation to create an aluminum oxide surface or dichromate seal on an aluminum part. This oxide layer is a combination of buildup on the surface of the part and penetration into the metal. This is the most common and cost-effective nickel acetate sealing process. Type II soft anodizing provides excellent abrasion and corrosion resistance. Except for dye castings, these coatings are easily dyed a wide range of colors.
