Refractory Metals - Composites -Special Alloys -
Ceramics -Tungsten - Titanium
Tungsten-Copper high
performance composites for electrical applications are made from
carefully controlled porous tungsten that is vacuum infiltrated
with molten copper. This provides a superior electrical contact
material that combines the refractory, long lasting wear
resistant properties of tungsten with the high thermal and
electrical conductivity of copper.
