When selecting finishes, select the RoHS compliant finishes. They are better for the environment and less expensive!

Finishes

This page lists all of the finishes and finish suffixes that DFCI has ever supported.

  • RoHS Compliant Finishes These are finishes that comply with RoHS (Restriction of Hazardous Substances) regulation requirements.
  • Standard Finishes These are standard finishes that have been and are still available.
  • Obsolete Finishes These are finishes that were available but have been discontinued. This section is here primarily for historical reference.

Optional finishes require special charges. Any order for a finish which is not listed as standard for that item will result in additional charges and lead time.

Cadmium plate (QQ-P-416) and hexavalent chromates are not RoHS compliant.

Cadmium plate and hexavalent chromates are being replaced by Zinc plate (ASTM-B-633) with a trivalent chromate, topped with a clear sealer. Salt spray to corrosion is 100 hours minimum.

Trivalent chromate only comes in clear. Yellow and black can be achieved with a dye, but the dye does not increase the corrosion protection. (Black cost slightly more; Yellow is much more costly. Our suggestion is to use the Clear Finish whenever possible.)
