Anodizing for Your Aluminum Prototype Part

Anodizing Part


What is Anodizing?


Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Although many nonferrous metals such as titanium, magnesium can be anodized, aluminum is ideally suitable to anodizing.


The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. It is quite different from the surface finish such as painting or plating, the anodic oxide is difficult to peel off or chip. Regarding to the porous structure and highly ordered, the anodic oxide can be coloring during the process.


How to Anodize an Aluminum Prototype Part?


Anodizing is accomplished by immersing the aluminum into an acid electrolyte bath and passing an electric current through the medium. A cathode is mounted to the inside of the anodizing tank; the aluminum acts as an anode, so that oxygen ions are released from the electrolyte to combine with the aluminum atoms at the surface of the part being anodized. Anodizing is, therefore, a matter of highly controlled oxidation—the enhancement of a naturally occurring phenomenon.


Benefits from Anodizing


Aluminum Prototype Part after anodizing can have longer life span, it can be increased resistance to wear and corrosion.

Anodizing allows a stable color coating, the exterior anodic on aluminum is not easy to peel or chip.

Anodizing provides good aesthetics to your aluminum prototype, a wide range of color can be available and allows the aluminum to maintain its metallic appearance.
