Metals
All the metals used Weidmüller are
selected and processed with their
surfaces treated according the latest
technical standards. The
surface protection conforms the
highest standards, matched the
special requirements the connection
systems used and RoHS-compatible
(RoHS Restriction Hazardous
Substances). The nickel coating
provides effective protection against
the loss zinc atoms from the brass.
Materials
Conductive materials
The current-carrying materials copper,
brass and bronze are characterised a
high conductivity plus good mechanical
properties.W.
In order guarantee the long-term
solderability (shelf life), the brass parts are
given additional nickel coating
as diffusion barrier.
Solder connections are also given a
coating tin. Experience gained from
storage outdoor test racks different
locations (industrial, marine, tropical and
normal atmospheres) has been incor-
porated into the design the surface
protection.
In the presence electrolyte, zinc

zinc migrate the steel, which provides
long-term protection for the parent metal.
Steels
Steel parts are electrogalvanised and
treated with additional Weidmüller
passivation technique, WInQ®
. The surfaces are usually given
a coating tin, which creates an
extremely good, “malleable” contact
