Processes

What is Anodizing?


Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized.

The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so cannot chip or peel. It has a highly ordered, porous structure that allows for secondary processes such as coloring and sealing.

Anodizing is accomplished by immersing the aluminum into an acid electrolyte bat 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.

Color Anodizing

Color anodizing is simply dying an item after it is anodized but before sealing, it is purely decorative and does not add or detract from the durability of the finish. We offer black, blue, red, green, purple and gold.

Splash Anodizing

Splash anodizing is a multicolor dying process that allows us to put two, three and even four colors on a part to really make it stand out.



Bright Dip Anodizing

Bright dip anodizing is an electrochemical polishing process that smooths the high spots on a part to give a finish much like plating, after bright dip the part can then be colored.
