Applications of Tungsten Copper Electrodes
Resistance Welding
W-Cu is suitable for electrode components exposed to electrical current, heat, pressure, and repeated contact. Spot-welding tungsten copper electrodes are suitable for resistance welding applications where electrical conductivity, heat dissipation, and wear resistance are required.
EDM Machining
W-Cu electrodes are suitable for electrical discharge machining because they combine good electrical conductivity with resistance to arc erosion and wear.
Electrical Contacts
Tungsten copper is suitable for electrical contacts exposed to high current, electrical arcing, and repeated switching.
High-Temperature Components
The material is also used for heat sinks, furnace components, vacuum contacts, and other parts exposed to high temperatures.
FAQ
Q: What is a tungsten copper electrode?
A: A tungsten copper electrode is a composite material that combines the electrical and thermal conductivity of copper with the hardness, wear resistance, and high-temperature stability of tungsten.
Q: What are tungsten copper electrodes used for?
A: Tungsten copper electrodes are commonly used for EDM, resistance welding, electrical contacts, arc contacts, and other applications requiring electrical conductivity and wear resistance.
Q: What is the difference between W50Cu50 and W80Cu20?
A: W50Cu50 contains more copper and generally provides higher electrical and thermal conductivity. W80Cu20 contains more tungsten and generally provides higher hardness, density, and resistance to wear and arc erosion.
Q: Can tungsten copper electrodes be customized?
A: Yes. Composition, dimensions, shape, surface finish, and machining details can be customized according to drawings or application requirements.
Q: Which tungsten copper electrode grade should I choose?
A: The appropriate W-Cu grade depends on the required electrical conductivity, wear resistance, thermal performance, and operating conditions. Send us your application requirements and specifications for grade selection.
