introduce

Tungsten copper alloy is a composite material that combines the high thermal and electrical conductivity of copper with the high melting point, strength, and arc resistance of tungsten. This unique combination makes W-Cu alloys ideal for applications that require excellent thermal management, electrical performance, and resistance to wear and extreme temperatures.

Typically manufactured through powder metallurgy, W-Cu alloys are available in various compositions (commonly 70W/30Cu, 80W/20Cu, etc.) to meet different functional requirements. These alloys are widely used in aerospace, electronics, power generation, and metalworking industries.

Key Features:
- High thermal conductivity (up to 250 W/m·K)
- Excellent electrical conductivity
- High arc erosion resistance
- Low thermal expansion
- Good machinability compared to pure tungsten
- Stable performance under vacuum and high-temperature conditions
Common Applications:
- Electrical contacts and circuit breakers in high-voltage equipment
- Electrodes for EDM (Electrical Discharge Machining)
- Heat sinks and thermal spreaders in high-power electronics
- Rocket nozzle liners and aerospace components
- Resistance welding electrodes and tooling components
Material Grades (Typical):
- WCu70 (70% W / 30% Cu): Better conductivity, suitable for EDM and welding
- WCu80 (80% W / 20% Cu): Higher strength and arc resistance, ideal for heavy-duty contact components
