WebThis limits the use of chromic acid anodizing as a decorative finish, but it can be dyed black for use as a non reflective protective coating on the optical component housing. Compared with the conventional sulfuric acid black anodizing treatment, even the black dyed chromium anodizing treatment is lighter in appearance (particle size). WebBlack Anodize Standards-Based Process Our acid etch anodize and caustic etch anodize processes meet Type II Class 1 performance standards. These specifications provide a benchmark for high-quality anodize coatings throughout the aluminum finishing industry.
