Chemical Film Coating is also known as Chem-film,
Chromate Conversion, Alodine, and Iridite.
Chem-film, or chromate conversion coating, is a
process for coating aluminum with a
chromium-based compound. It offers excellent
atmospheric corrosion resistance and is also a
wonderful primer coat for paint or other organic
coatings. It is thinner than anodic coatings.
Chromate (chem-film) coatings can be done in
either clear or yellow. The MIL-SPEC for Chem-film
is Mil-C-5541E Class 1A.

- Protects from corrosion
