Functional and Decorate Coatings for Aluminum Components
Anodizing is an electrochemical process for producing controlled aluminum oxide films on aluminum. Oxide forms naturally on untreated aluminum, but the anodizing process produces a coating which is uniform, much harder, and more dense than natural oxidation. Aluminum oxide also possesses excellent thermal and electrical insulating qualities.
Anodizing, unlike electro-plating, penetrates and then grows on the base metal by converting aluminum to aluminum oxide. Proper formation of aluminum oxide coatings, known as aluminum anodizing, creates a natural decorative appearance as well as an increased resistance to corrosion and abrasion.
