About
Aluminum anodizing is an electrochemical process that creates an aluminum oxide film that is electrically non-conductive, protects the aluminum against corrosion, and is resistant to wear. Anodization is used for a range of products from firearms and sporting goods, to electronics, machinery, and cookware. It can be used in conjunction with our Teflon Coating.
Types I, II, III
- Type I, Chromic: Thin film formed in chromic acid, mostly used in aerospace for corrosion protection
- Type II, Sulfuric: the most common form, produced in sulfuric acid, often used to protect and to dye certain colors
- Type III, Hard: hard anodize is a thick film that provides the greatest abrasion and corrosion resistance
Properties
- Corrosion Resistance: resistant to atmospheric and saltwater environs
- Electrical Insulation: dielectric (non-conductive)
- Paint Adhesion: creates an excellent surface for painting
- Adhesive Bonding: improves adhesion and resulting bond strength
- Sterilization: withstands hydrogen peroxide, which is commonly used in medical grade sterilizaion
