Durmalon Connector Finish
Alternative to Cadmium
Commercial, industrial & military markets are rapidly moving away from hazardous materials such as
Cadmium (Cd) & Hexavalent Chrome (Cr6+). Amphenol is offering an alternative finish & process that
complies with all customer requirements tied to these specifications.
DURMALON TM
Alternative to Cadmium
Cd & Cr6+ have been applied to numerous components of land, sea and air weapon systems for many years & provides sacrificial corrosion
protection for steels and excellent lubricity for threaded applications. However, Cd is a toxic metal and a known carcinogen. In addition, Cd is
plated from an aqueous bath containing cyanide salts. Cr6+ is a known carcinogen as well.
MIL-DTL-38999 rev L, controlled by the Defense Supply Center Columbus (DSCC) has established 3 new service classes as
alternatives to Cd.
• Class P Pure Dense Electrodeposited Aluminum (Alumiplate)
• Class T Nickel Fluorocarbon Polymer (Ni-PTFE)
• Class Z Zinc-Nickel (Zn-Ni)
Amphenol is using this & the European Union directive 2002/95-EC-RoHs (Restriction of Hazardous Substances) as direction to qualification for
all domestic, global, commercial, industrial & military specifications requiring the reduction or elimination of these hazardous materials.
At this time, we are focusing on Ni-PTFE, Durmalon, our internal part number coding “DT” finish. Amphenol Durmalon is now QPL’d (qualified)
by DSCC to MIL-DTL-38999 Rev L, Series III, Class T. The finish is also RoHS compliant due to the NON-use of Cr6+.
Amphenol also continues to develop a heavy duty Durmalon (Amphenol “DX” p/n code
designation) to support the JSF, F-35 program. This plating is intended to meet the additional higher corrosive Sulfur Dioxide (SO2)/salt fog
requirements of JSF.
Also under development & qualification testing is Zinc-Nickel (Amphenol “DZ” p/n code
designation) to comply with the new D38999 class “Z” finish requirements.
Amphenol’s Durmalon like Olive-Drab Cadmium plating (Class W), meets 500 hours of Salt Spray,
combined with 500 mating cycles and maintains less than a 2.5 millivolt drop shell-to-shell conductivity.
Of all platings tested, Durmalon has been proven to meet these requirements and is also being tested
under development & showing positive results for the following:
• Sulphur Dioxide (SO2) corrosion requirement of the JSF Program
• Potassium Formate- Deicer fluid testing performed by Boeing
Please consult the factory for availability.
Applications
Interest for non-hazardous
alternative finishes is gaining
momentum & many customers
are currently using Durmalon.
As mentioned above,
Amphenol is developing a
“Heavy Duty” version of
Durmalon to comply with
the higher level requirements
by Lockheed Martin for the
F-35, Joint Strike Fighter (JSF)
program. The requirements
include 2000 hrs of neutral salt
fog exposure & an acidic salt fog
environment exposure with added
sulfur dioxide (SO2) for 336 hrs.
Please contact the factory
for availability.
Testing
Amphenol Aerospace has
performed extensive testing on
14 alternative platings with the
most consistent performer being
Durmalon. Please contact
