Tungsten copper (W-Cu) alloys, thanks to their unique combination of physical and chemical properties, play an irreplaceable role in the field of electrode materials. By integrating tungsten's high melting point, hardness, and density with copper's excellent electrical and thermal conductivity, W-Cu alloys have become the preferred choice for various high-strength, heat-resistant, and arc-resistant electrode applications.

Key Performance Advantages
As an electrode material, tungsten copper offers the following outstanding features:
1.High Temperature and Arc Resistance: With a melting point of 3410°C, tungsten ensures the electrode maintains structural stability under high-temperature arc discharge conditions—ideal for frequent, high-current operations.
2.Excellent Electrical Conductivity: The copper component provides high conductivity, ensuring efficient current transfer with minimal energy loss.
3.Superior Thermal Conductivity: Efficient heat dissipation lowers operating temperatures and enhances service life and performance stability.
4. Outstanding Wear Resistance: Capable of withstanding repeated mechanical contact and stress, ideal for automated production requiring long-lasting electrode performance.

Typical Applications
1.Electrical Discharge Machining (EDM) Electrodes
W-Cu electrodes are widely used in precision mold making and hard material shaping due to their low electrode loss, high machining precision, and excellent surface finish. Especially in the processing of complex geometries, their stable discharge performance significantly improves productivity and mold quality.

2.Resistance Welding Electrodes
In resistance welding applications such as spot welding and seam welding—common in automotive manufacturing and electronics assembly—W-Cu electrodes are ideal for welding high-strength steels, stainless steels, and coated metals. Their high-temperature resistance, anti-adhesion properties, and long service life make them suitable for robotic and automated welding systems.

3.Vacuum Circuit Breakers and High-Voltage Discharge Electrodes
Tungsten copper is a preferred material for arcing contacts in vacuum interrupters, lightning arresters, and other high-voltage components. Its strong arc erosion resistance ensures reliability and safety during repeated discharges, significantly extending product lifespan.

4.Plasma and Spark Plug Electrodes
In plasma generators and spark plugs used in internal combustion engines, W-Cu electrodes withstand high-frequency discharges and corrosive gas flows. Their durability and resistance to wear make them ideal for these harsh environments.

5.Gas Discharge and Surge Protection Components
W-Cu alloys are also used as anodes or cathodes in gas discharge tubes and surge protection devices. Their excellent energy absorption capacity allows them to endure high-energy impacts from repeated discharges without performance degradation.

Product Forms and Customization
W-Cu electrode materials are available in a variety of forms, including rods, plates, electrode tips, and customized parts. Manufactured via powder metallurgy and vacuum infiltration processes, copper content can be precisely controlled (typically between 10–50%) to balance electrical conductivity and arc resistance for different applications. We offer CNC machining and surface treatment services based on customer designs to support integration into automated production lines.
