High-Quality Conversion Coating

Industrial Anodizing Co. Inc. provides chemical conversion coatings for aluminum in accordance with Mil-C-5541 Classes 1A and 3, AMS 2473 and 2474, or your specific specification, in either a bright or matte finish.

Chromate conversion coatings are produced on aluminum and its alloys by immersion. They are generally non-crystalline, nonporous and amorphous. Chromate conversion coatings are widely used in the metal finishing industry to retard corrosion, as a base for paints and as decorative finishes.

Chromate conversion coatings are often referred to as Iridite, Alodine or chem film. It should be noted that Iridite and Alodine are trade names for chemicals used to produce chromate conversion (chem film or chemical film) coatings.
Conversion Coating

A Good Base for Paint or Adhesive Applications

Chromate can be used as a base for paint or adhesive applications and can also be electrically conductive. This coating is offered in yellow iridescent to clear iridescent. The electrical resistance will increase with the darkness of the coating.

TCP conversion coating meets the same requirements as standard conversion coating. TCP coating is RoHS compliant, replacing conventional hexavalent chromate conversion. Since you are replacing the hexavalent chrome, you will no longer have the yellow finish. TCP coating will appear as a clear iridescent coating on aluminum.

Our size capabilities go up to 11 feet.

Key Benefits and Capabilities of Conversion Coating

  • Outstanding paint adhesion
  • Electrical conductivity
  • Good corrosion resistance
Capabilities
  • Type I
    Hexavalent chrome-based coatings
  • Class 1A
    Class 1A coatings (often referred to as Alodine coatings) are used when electrically conductive, maximum corrosion protection is desired. The color of these coatings is generally golden-yellow to olive in appearance. Class 1A coatings can be applied to pieces up to 11' L x 9' H and meet the requirements of AMS-2473. Please contact us for your specific needs
  • Class 3
    Class 3 coatings (often referred to as Iridite coatings) are used when lower electrical resistance is required. The color of these coatings generally ranges from a slight iridescent to straw color. Class 3 coatings can be applied to pieces up to 11' L x 9' H and meet the requirements of AMS-2474. Coloration of the coating can be tailored to your specification
  • Type II
    Non-hexavalent chrome-based coatings
We have added non-hexavalent chromium pretreatment to our chemical conversion films. This is a RoHS-compliant coating.

After a great deal of research, we have installed a tank with a licensed version of the U.S. Navy's Trivalent Chromium Pretreatment (TCP). This alternative to Alodine and Iridite provides Class 1A corrosion protection and paint adhesion and Class 3 electrical characteristics at the same time.
