Sulfuric Acid Anodizing exhibits excellent corrosion resistance, very good abrasion resistance, and the coating is an electrical insulator. It can be applied without a subsequent dye step (clear), or dyed after anodizing. Thicknesses of the coating are generally in the 0.0002″ – to 0.0009″ range. We can coat parts as large as 78″ long x 80″ deep x 22″ wide.
