Key Properties
1. Extreme Hardness & Wear Resistance – The 90% tungsten composition ensures exceptional strength and durability, making it highly resistant to mechanical wear and deformation.
2. Low but Sufficient Electrical & Thermal Conductivity – While conductivity is lower than alloys with more copper, it remains adequate for specialized high-performance applications.
3. Outstanding Arc & Erosion Resistance – The high tungsten content provides superior resistance to electrical arcing, reducing material degradation in high-voltage electrical applications.
4. Minimal Thermal Expansion – Offers excellent dimensional stability under extreme temperatures, making it ideal for applications with high thermal and mechanical stress.
5. Difficult but Precise Machinability – Due to its high hardness, W90Cu10 is challenging to machine but can be processed with advanced machining techniques such as EDM (Electrical Discharge Machining).
Applications
- High-Voltage Electrical Contacts & Switch Components – Used in circuit breakers, vacuum interrupters, and relays that require maximum arc resistance.
- Electrical Discharge Machining (EDM) Electrodes – Provides exceptional wear resistance for precision machining applications.
- Heat Sinks & Thermal Management Components – Utilized in aerospace, defense, and power electronics industries for handling extreme heat loads.
- Resistance Welding Electrodes – Offers superior durability and minimal material loss for high-performance welding applications.
