Tungsten-Copper
for Electrical Application
Electrical
contacts are subjected to extreme mechanical and thermal stresses
during operation. For fractions of a second, temperatures rise to
several thousand degrees as a result of the arcing. Our
tungsten-Copper materials are used owing to their unique physical
properties.
Advantages: without other element
except Tungsten and Copper, uniform material, low content of gas
and impurity, very high burn-off resistance, excellent thermal and
electrical conductivity, all necessary joining and machining
processes.
