Anodizing

Our Details

Knowledge

Type I Anodize:


Boric Anodize – Boric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a chromated, environmentally friendly solution.


Tartaric Anodize – Tartaric-Sulfuric Anodize (TSA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a chromated, environmentally friendly solution – typically specified in Airbus programs like the A350.


Chromic Anodize – Chromic Acid Anodize (CAA) creates the thinnest anodic coating, while providing the same corrosion resistance as other types of anodization, such as boric or sulfuric.


Type II Anodize:


Sulfuric Anodize – Sulfuric Acid Anodize (SAA) is used when hardness and abrasion resistance is required on a part, and creates a surface that is harder than traditional chromic anodizing.


Type III Anodize:


Hardcoat Anodize – Hardcoat anodize is created as a sulfuric acid bath, but results in a much thicker surface anode coating than traditional sulfuric acid anodizing.
