Anodizing (Type II)

Anodizing is an electrolytic process that forms an aluminum oxide film on the surface of the material. The oxide film that is formed grows from the base metal as an integral part of the material. Typically 60% of the thickness builds into the material and 40% builds up. This oxide is hard, and is corrosion and abrasion resistant with excellent wear properties. The natural color of anodizing is typically light silver in appearance but the coating can be dyed to meet customer color requirements. This coating is commonly referred to as Type II Anodizing. Dyed (Color) Anodizing will give your products a professional, attractive appearance. Team Metal Finishing standard colors are Red, Blue, Black, Green and Gold. Other colors available upon request.

All chemicals used in our Anodizing process are considered FDA “GRAS” (Generally Regarded As Safe) per Federal Regulation codes:
21 CFR 182, 21 CFR 184, 21 CFR 186

Hard-Coat Anodizing
(Type III)

Hard-Coat anodizing is similar to Type II Anodizing, but the film of aluminum oxide is produced at much higher current densities and with much colder temperatures. The result is a film that is greater in thickness and density, and is more wear and corrosion resistant than standard (Type II) anodizing. The natural color of hard coat is a darker shade of gray. Typically 50% of the thickness builds into the material and 50% builds up. Due to the natural color of the coating customers typically request black as the dyed color. Other dye colors tend to be much darker than anticipated because of the color that the hard coat produces. This coating is commonly referred to as Type III Anodizing.
