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historical reference.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.) RoHS (Restriction of Hazardous Substances) Compliant Finishes

NOTE: Some of the finishes listed may not always be available.
Availability may be affected by order quantity and lead time. Type of plating
ordered can affect lead time.
**** There may be some duplication in the finish codes for the older
finishes as the older finishes did not include specifications for the finish
thickness. Please select the current finish code for the appropriate thickness.
