    Aluminum Anodizing Process and Design Guide Accurate. The anodizing process using sulfuric acid process, which is common, has advantages of lower cost, rapid action and comparatively low operating voltage. The latter is a consequence of the high conductivity of the electrolyte and its ability to penetrate the film to the underlying metal. The electrolyte has a solvent action upon the film which affects its character (Franklin 1961). This process Anodising is an electrolytic process for producing thick oxide coatings, usually on aluminium and its alloys.
