What is the difference between anodizing and electropolishing?

The electrochemical polishing process is not the same as anodizing. The main goal of the anodizing process is to form a protective oxide film in the electrolyte to improve corrosion and wear resistance.

It does this by immersing the metal in a bath of acidic electrolytes, with an electric current passing between the anode and cathode.

Electropolishing, on the other hand, is used to remove roughness and clean the surface of metal parts. While the Anoplate specializes in deburring and polishing stainless steel using electropolishing, it can also be used on aluminum. Although different, electropolishing is also essential as a pre-treatment for the anodizing process, as it provides a smooth, decorative surface. In addition to providing a clean appearance, electropolishing eliminates surface damage and edge breakage. It is an excellent alternative to bright dip varnishes as it does not produce toxic fumes and does not corrode.
