Amphenol RoHS Compliant Platings
Alternative to Cadmium
DURMALON
DURMALONTM
Amphenol’s Answer to EU RoHS/ELV/Cadmium Free Restrictions
Commercial, industrial & military markets are rapidly moving away from restricted
materials such as Cadmium (Cd) & Hexavalent Chromium (Cr(VI)). Both of these
restricted materials are toxic and are known carcinogens. Amphenol is offering
an alternative finish that complies with all customer requirements tied to these
specifications.
TM
Alternative to Cadmium
I
SJT
Access
Cadmium has been applied to numerous components of land, sea and air weapon
systems and NASA systems for many years as it provides sacrificial corrosion
protection and excellent lubricity for threaded applications.
The Defense Logistics Agency (DLA) has added the following cadmium alternative
finishes to MIL-DTL-38999, Rev L (and other connector specs):
• Nickel Fluorocarbon Polymer
• Zinc-Nickel
AMPHENOL’S DURMALONTM
Durmalon, like Olive-Drab Cadmium plating (Class W), meets 500 hours of dynamic
salt spray, combined with 500 mating cycles and meets specified millivolt drop shellto-shell conductivity. Durmalon also meets a 200° C temperature rating. Durmalon
has been proven to meet this requirement as well as Potassium Formate-Deicer fluid
testing performed by Boeing.
BLACK ZINC NICKEL
Black Zinc Nickel is Amphenol’s 2nd RoHS Compliant Plating Alternative
to Cadmium Amphenol is now offering a new RoHS compliant alternative to Cadmium. Black Zinc Nickel is a non-reflective and conductive
black finish approved for 500 hrs salt spray making it an excellent choice
for harsh environments. Black Zinc Nickel has been qualified by the
DLA, with internal part number coding “DZ” finish, which meets or
exceeds the 38999 designated class “Z” finish. Black Zinc Nickel is
compatible with other platings and available on a wide variety of
connectors and accessories including all MIL-DTL-38999 Series III
connectors.
APPLICATIONS
APPLICATIONS
Interest for non-hazardous alternative
finishes is gaining momentum & many
customers are currently using Durmalon
for a broad number of applications.
Durmalon
combines
the
unique
lubrication and anti-wetting properties of
PTFE with corrosion resistance, high
conductivity and EU RoHS compliance
in a non-reflective finish.
TESTING
Amphenol Aerospace has performed
extensive testing on numerous alternative
platings with the most consistent
performer
being
the
Durmalon.
For specific applications please contact
Amphenol Aerospace.
