Durmalon
Alternative to Cadmium
Cadmium has been applied to numerous components of land, sea and air weapon systems and NASA systems for many years, due to its
desirable functional qualities. Cadmium provides sacrificial corrosion protection for steels and excellent lubricity for threaded applications. In
addition, Cadmium is easily electroplated onto a number of different metallic substrates and various geometries including internal diameters,
threads, and more complex components.
However, Cadmium is a toxic metal and a known carcinogen. In addition, Cadmium is plated from an aqueous bath containing cyanide salts.
For these reasons many companies are seeking to reduce dependence on or eliminate Cadmium from use on new applications.
Recently, Defense Supply Center, Columbus (DSCC) added three Cadmium alternative finishes to MIL-DTL-38999, Rev L
(and other connector specs):
Amphenol’s Durmalon
The Olive-Drab Cadmium plating (Class W) over aluminum shells has long been the preferred finish for Military and Aerospace
applications. 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 this requirement and several newer requirements:
RoHS
The European Union Directive 2002/95/EC- RoHS (Regulation of Hazardous Substances) has put a ban on both Cadmium and hexavalent
Chromium, which is a top layer post treatment on the OD Cad plating. Durmalon is RoHS compliant.
Applications
A number of Amphenol customers
are currently using Durmalon.
Lockheed Martin has tested
and approved it for use on
the F-35 Joint Strike Fighter
program.
They are currently
evaluating Amphenol’s
Durmalon plated 38999
connectors in 2000 hour
salt spray testing and
500 hour SO2 testing.
Testing
Amphenol Aerospace has
performed extensive testing
on 14 alternative platings
with the most consistent
performer being the Durmalon.
The most recent testing is
documented in Amphenol
Test Report ER-8799.
