advantage surface protection with zinc lies the high
corrosion protection effect. Furthermore, the presence of
an electrolyte, zinc acts cathode (i. Besides corrosion protection, this ensures high
contactability, which leads low contact resistance. order permanently maintain the contact force,
the steel parts are electrogalvanised and provided with
additional passivation means chromate layer. negative) with
respect steel.
Steels
Steel ensures mechanical stability for all our connection
systems.Metals
The metals use are selected and processed with their
surfaces treated according the latest technical knowledge.
Conductive substances
The current-carrying materials copper, brass and bronze
are characterised high conductivity plus good
mechanical properties.
C. The metal ions the zinc migrate the
steel.
The nickel coating provides effective protection against
outward diffusion zinc atoms from the brass.
In addition, our welding area certified accordance with
DIN ISO 3834-3 for fusion welding metal-based materials. This protects the underlying material from attack. order to
guarantee long-term solderability, additional nickel
coating applied the brass parts diffusion barrier. also effective for long
time, even after the zinc coating has been partially damaged
by scratches pores
