Chromate Conversion Coating

MIL-DTL-5541 Type I and II, AMS 2473

This process is also known as Chemfilm or Alodine. The process involves immersing aluminum in a hexavalent or trivalent chromate. The chromate is gelatinous, and because the film it produces on the aluminum is fragile it should not be handled for up to 24 hours. It typically leaves a light iridescent to dark gold glint. It is commonly applied to items prior to painting to increase corrosion resistance and adhesion. Chromate conversion coatings differ from anodized coatings in that they are used to give corrosion resistance while still maintaining electrical conductivity.

Benefits of Chromate Conversion:

  • Helps prevent corrosion
  • Retains conductive properties of aluminum.
  • Good basis for paint
