Yellow Iridite




Looking for specification for yellow Iridite on aluminum.

Edward J. Leszczak

Iridite (with a single 'r') is a Macdermid trade name for (among other things) a qualified product for MIL-C-5541 chromate conversion coating, Edward. That mil spec may be what you are looking for.

How do we look into the RoHS Directive regarding the elimination of the hexavalent chromium linked to the 5541 ?
of course in civilian/computer/telecom equivalent for passivation on aluminium and iron plates?

Until recently trivalent chromates generally had little success replacing Hex chrome materials that meet MIL-C-5541 requirements. There is now a group of products that compare favorably with the hex chem films. These should shortly be on the QPL list and meets or exceeds the requirements of MIL-C-5541.
