Chemical conversion coating (also known as chemical film, chromate conversion coatings, chromating, alodine and alodining) provides economical corrosion protection and a superb surface for painting and powder coating aluminum parts.
Unlike anodizing, which creates a non-conductive coating, chemical conversion coatings provide a low electrical resistance and preserve the electric conductivity of your aluminum parts. Chemical conversion coatings also do not require electricity and therefore are more economical. All parts go through a multi step surface cleaning process prior to being coated.
While Chromating is typically either clear or coloured, Altech only offers clear at this time.
