Hard Anodizing is carried out in a sulfuric acid bath at a low temperature. This produces a coating with much greater resistance and hardness than normal anodizing.
The shade of the pieces depends on the aluminum used. At Anodfarbe we offer the option of Hard Anodizing in black, so that it is possible to anodize different aluminums, maintaining the same color.

Chemical Nickel is a substance used in the coating of various products, such as automobile parts and industrial equipment. Anodfarbe uses Chemical Nickel with a high phosphorus content, which provides a uniform coating thickness, regardless of the geometry of the part.
