Explanation of the Color Anodizing Process

Color anodizing is a surface treatment process that involves enhancing the natural oxide layer on aluminum components. It is achieved through an electrochemical process called anodization. During anodization, the aluminum part acts as the anode in an electrolytic cell, and a direct current is passed through it while submerged in an electrolyte solution.

This controlled oxidation process thickens the aluminum’s natural oxide layer, creating a porous surface. The pores in the surface act as a receptacle for dyes or pigments, allowing the color to penetrate and become an integral part of the part itself. After dyeing, the part is sealed to lock in the color and improve the corrosion resistance.
