Aluminum Hard-Coat Anodizing

Type III Industrial Anodizing

Certified Metal Finishing is Nadcap Accredited for Hardcoat Anodizing which is a non-conductive aluminum oxide metal finish formed by an electrochemical process. Hardcoating adds strength to standard aluminum resulting in a corrosion and wear resistant coating.

Hardcoating is accomplished by immersing your aluminum alloy components into an electrolyte solution. The aluminum oxide that is formed on the surface is uniform, denser, and much harder than natural oxidation with a Rockwell C-scale rating of 60. The hardcoat penetrates the base metal as much as it builds up on the surface becoming an integral part of the aluminum strengthening and extending the working life of your components and/or parts.

Hard coating allows the use of aluminum alloys in many design applications that were formerly restricted to steel.
