Type II Anodize

Overview

Type II Anodizing, also known as regular or Sulfuric Anodizing, is the process of using electrolytic oxidation to create an aluminum oxide surface on an aluminum part. This oxide layer is a combination of buildup on the surface of the part and penetration into the metal. The typical ratio of penetration vs. build up 70 penetration / 30 build up. The result is a finish that gives the part better wear and corrosion resistance and a surface that can be easily colored to fit the application.

High purity aluminum alloys work best with Type II Anodizing. They produce the best clarity and color of the coating. All wrought aluminum alloys and most types of aluminum die castings can be anodized. The porous structure of the oxide coating created by Type II Anodizing allows for color infusions and makes a high-quality base for paint, powder coating, electroplate, adhesives, organic dying and lubricity agents.

The anodizing process is one of the more environmentally-friendly metal finishing processes. The most common by-products can be recycled in the manufacturing of baking powder, cosmetics, newsprint, and other items.
