2017-04-13 Aluminum anodizing is an electrochemical process in which an oxide (anodic) layer is chemically built on the surface of the metal. This oxide layer acts as an insulator and can be dyed in a wide variety of colors. Anodizing provides surface corrosion protection along with an excellent substrate for decorative finishes.

ANODIZING. Anodizing is one of the most common surface treatments of aluminum. In all anodizing processes, the basic reaction is conversion of the aluminum surface to aluminum oxide. The aluminum part, when made anodic in an electrolytic cell, causes the oxide layer to become thicker, leading to better corrosion and wear resistance.
