Type I Chromic Anodize
When using chromic acid for precision anodizing, the acid enhances corrosion resistance in the aluminum parts. This process produces a thin opaque film that is self-healing to a degree, along with being soft, non-conductive, and ductile.
Type II Sulfuric Anodize
Our NADCAP anodizing services provide a multitude of uses, depending on the type. The process of using electrolytic oxidation to create an aluminum oxide surface on an aluminum part is called Type II Anodizing. It can also be referred to as regular anodizing or sulfuric anodizing.
Type III Hardcoat
The most durable commercial anodizing possible is the Type III hardcoat. This coat will resist wear on electroless nickel and hard chrome for years to come.
In order to keep all defined areas protected, we use masking to keep every inch of the material safe from being exposed throughout the anodizing process.
