Black Oxide

Chem Film Coatings for London and Beyond

We offer Alodine, Iridite and Metalast conversion coatings on aluminum. All are used as a primer coating before paint. Alodine and Metalast are clear conversions, and the parts look nearly the same as they did before the conversion. Iridite, however, is a yellow/ gold color when it is finished. We do both to MIL-DTL-5541 or equivalent.

If you have any questions regarding chemical conversion coatings, please call us at our London facility.
