The ability of aluminium to compete in markets where a high standard of finish is essential has depended upon the development of chemical polishing processes, sometimes also referred to as “bright dipping”.

It must therefore be appreciated that the final finish obtained depends on the combination of material, brightening treatment and anodizing process employed, the combination often being referred to as “bright anodizing”.
