Key Properties
1. High Hardness & Wear Resistance – The increased tungsten content enhances durability, making it suitable for high-stress environments.
2. Moderate Electrical & Thermal Conductivity – While conductivity is lower than alloys with more copper, it is still sufficient for specialized electrical and thermal applications.
3. Excellent Arc & Erosion Resistance – The high tungsten content significantly improves resistance to electrical arcing, reducing material degradation in electrical applications.
4. Low Thermal Expansion – Offers better dimensional stability compared to pure copper or lower tungsten-content alloys, making it ideal for high-temperature environments.
5. Good Machinability – Though harder than W70Cu30, it can still be processed using appropriate machining techniques.
Applications
- High-Voltage Electrical Contacts – Used in circuit breakers, vacuum interrupters, and high-power switches due to its excellent arc resistance.
- Electrical Discharge Machining (EDM) Electrodes – Provides superior wear resistance for precision machining applications.
- Heat Sinks & Thermal Management Components – Suitable for aerospace and power electronics where thermal stability is critical.
- Resistance Welding Electrodes – Offers a balance between conductivity and mechanical strength, making it effective for welding applications.
