Boric
Boric sulfuric acid anodize was developed by the Boeing Company as a chromic acid anodize replacement for non-critical fatigue parts.
Boric sulfuric acid anodize's applications have grown as environmental concerns have discouraged the use of chemistries containing chrome. Paint adhesion is equal or superior to chromic acid and the boric sulfuric process is more energy efficient than chromic acid anodize. This coating is primarily used on aircraft, electronics, and OEM machined parts due to its excellent paint base and lack of a corrosive residue in rivited or welded joints.
