Key Properties
1. Exceptional Hardness & Wear Resistance – The high tungsten content significantly enhances mechanical strength, making W85Cu15 highly resistant to wear and mechanical stress.
2. Moderate Electrical & Thermal Conductivity – Although conductivity is lower than lower tungsten-content alloys, it remains suitable for specialized electrical applications.
3. Superior Arc & Erosion Resistance – The high tungsten content provides excellent resistance to electrical arcing and erosion, making it ideal for high-voltage electrical components.
4. Low Thermal Expansion – Offers outstanding dimensional stability under extreme temperatures, reducing deformation risks in high-temperature environments.
5. Challenging but Machinable – Due to its high tungsten content, W85Cu15 is more difficult to machine than alloys with higher copper content, but it can be processed using advanced machining techniques.
Applications
- High-Voltage Electrical Contacts & Switch Components – Used in circuit breakers, vacuum interrupters, and relays requiring high arc resistance.
- Electrical Discharge Machining (EDM) Electrodes – Provides superior durability and wear resistance for precision machining.
- Heat Sinks & Thermal Management Solutions – Utilized in aerospace, power electronics, and semiconductor industries to handle high heat loads.
- Resistance Welding Electrodes – Offers excellent wear resistance and thermal stability for demanding welding applications.
