Chromating or Chromate conversion coating is an economical replacement for anodizing when abrasion resistance is not required. Chem-Film provides an excellent paint adhesion and a superior base for bonding. Aluminum parts achieve a higher corrosion resistance when Chem-Film is applied. Chromate leaves no measurable build-up, and provides excellent corrosion resistance. Alodine and Irridite are some of the trade names associated with this process.

Mil-C-5541 Class 1A provides the heaviest coating, while Class 3 is a lighter variation where low electrical resistance is required. Colors available are clear or gold.

»  MIL-C-5541, CLASS 1A and 3
