Anodization is a process that creates a uniform layer of oxidation on the surface of parts. This layer of oxidation is harder and more durable than the underlying aluminum. The hardness helps lessen the effect of normal wear and tear, increasing the lifespan of the parts. It can also help prevent thread galling and other damage to parts.
Another perk of anodization is it allows color to be added to parts.
Anodized parts make your life easier and your work more efficient by providing a longer lifespan, easier maintenance, and an increased tolerance for heavy duty use.
