Anodized Aluminum Circle for Cookware
Anodized Aluminum Circle for Cookware

Anodizing is an electrolytic process that produces a dense, chemically stable protective aluminum oxide film that is an integral part of the underlying aluminum---it cannot peel or flake off. Most films produced by anodizing are translucent and so show the silvery look of the aluminum but various colours are achievable by a varity of anodizing process variations. The main type of anodizing process used for general purpose is based on a sulphuric acid electrolyte, producing an ideal combination of decorative and protective properites. The sealing of the anodic film in boiling water after anodizing is an important part of the surface treatment.

Anodizing enhances the natural qualities of aluminum still further; it permits a strongly contemporary finish with incomparable corrosion and abrasion resistance.
