Tungsten Copper
Tungsten alone is a very brittle metal with a high melting point, however the combination of copper and tungsten delivers a relatively hard material with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
Copper Tungsten Applications
- Arching contacts
- Spark erosion and electro-chemical machining
- Spot welding
- Projections welding
- Crosswire and butt welding
