Anodizing Process

Anodizing is an electro-chemical process that forms a durable, oxide coat on the surface of aluminum extrusions. The anodizing is accomplished by immersing an aluminum extruded profile in a tank containing an acid-based electrolyte and an electric current is passed through the solution. The aluminum extruded profile serves as the anode, the tank the cathode. The electrolyte releases oxygen ions at the surface of the profile which immediately combines with the surface aluminum to form a hard aluminum oxide film.

Types of Anodizing

Sulfuric (the most common process) produces comparatively thick, transparent and absorptive oxide film, suitable for receiving both organic and inorganic dyes, and metal oxides for electrolytic color. Hard Coat anodizing produces a much thicker film. Hard Coat anodizing is a modification of sulfuric anodizing, performed at high current densities and lower seal temperatures. Sometimes additives are mixed into the electrolyte to produce a denser, more abrasion-resistant oxide film, imparting high wear resistance to the product.
