TYPE II CONVENTIONAL ANODIZING
Type II sulfuric acid anodizing is an electrochemical process that causes aluminum oxide to form to a desired thickness on the surface of aluminum and aluminum alloys. Type II anodizing increases durability, corrosion resistance and aesthetic appeal, as well as makes the aluminum surface electrically non-conductive.
Conventional Anodizing Advantages:
- Corrosion Resistant …Comparable to Stainless Steel¹
- Surface Hardness …Increased Scratch Resistance¹
- Conductivity …Non-conductive up to 1000 V¹
- Aesthetics …Many color choices
- Color Durability …Colors remain vibrant and fade resistant
- More Finish Options …Excellent base for a wide range of finishing options (Clear Coat, Paint, Graphic Applications, etc.)
