Materials
.e. The metal ions the zinc migrate the
steel. Besides corrosion protection, this ensures high
contactability, which leads low contact resistance.Metals
The metals use are selected and processed with their
surfaces treated according the latest technical knowledge.
In addition, our welding area certified accordance with
DIN ISO 3834-3 for fusion welding metal-based materials.
Conductive substances
The current-carrying materials copper, brass and bronze
are characterised high conductivity plus good
mechanical properties.
