Tungsten-Copper for Electric Applications
 |
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. |
