Tungsten-Copper Alloys for Electric Applications
Tungsten-Copper Alloys 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.
Electric Application: Contacts
High Voltage Arc Contacts, Vacuum Contacts, Electrodes for Resistant Welding and Spark Erosion, Leaders for Steel Rolling, Dies for Casting, Balance Weights, Rocket Parts.
