Aluminum Anodizing

Aluminum Anodizing

Anodizing is an electrochemical process producing decorative and protective finishes on aluminum parts and products. Parts to be anodized are mounted on special racks that grasp, and allow a specified amount of electrical current to reach each piece.

Aluminum parts, require the natural oxides and oils to be removed prior to Anodizing therefore, parts must undergo a pretreat, usually involving a series of mild cleaners as well as an Etch or deoxidize solution.

The Anodizing takes place in an electrolyte solution of Sulfuric acid which converts the aluminum to aluminum oxide. . This aluminum oxide can be produced in thicknesses from as little as .0001 up to .0008 thick allowing for enhanced durability and organic dye absorption.

Following Anodizing, the parts can be dyed using a wide variety of color dyes to achieve an extensive spectrum of finishes. The parts are then sealed, locking in the desired color, and producing a high quality, durable finish.
