Chem Film, commonly known by their brand names: Alodine and Iridite, is a chemical conversion coating process that is used to passivate aluminum.

Chem Film protects aluminum substrates from corrosion and serves as a base for organic coatings while leaving dimensions unchanged.

Chem Film per MIL-DTL-5541 Class 3 is electrically conductive. The best corrosion protection is provided by Chem Film perMIL-DTL-5541 Class 1A.

Mspecs offers both trivalent clear (RoHS compliant) and hexavalent yellow chromium based Chem Film.
