Tungsten Copper (W-Cu) Material – The Perfect Combination of Strength and Conductivity

Introduction:

Tungsten Copper (W-Cu) is a high-performance composite material made by combining tungsten (W) and copper (Cu) through advanced powder metallurgy processes.
It offers an exceptional blend of the high-temperature strength, hardness, and wear resistance of tungsten, along with the excellent electrical and thermal conductivity of copper.
This unique combination makes Tungsten Copper an ideal solution for demanding applications where extreme heat, electrical stress, and mechanical wear are present.

Key Features:

• High Thermal Conductivity: Quickly dissipates heat under high-load conditions.

• Excellent Electrical Conductivity: Ideal for electrical and EDM (electrical discharge machining) applications.

• Outstanding High-Temperature Resistance: Retains strength and hardness even at elevated temperatures.

• Superior Wear and Arc Resistance: Extends service life in harsh working environments.

• Good Machinability: Despite its density, W-Cu can be precision-machined into complex shapes.

Typical Compositions:

Tungsten copper materials are available in different grades depending on tungsten content, such as:

• WCu50 (50% W, 50% Cu)

• WCu70 (70% W, 30% Cu)

• WCu75 (75% W, 25% Cu)

• WCu80 (80% W, 20% Cu)

• WCu90 (90% W, 10% Cu)

Higher tungsten content = greater hardness and high-temperature strength;
Higher copper content = better electrical and thermal conductivity.

Applications:

• Electrical Contacts: Circuit breakers, switches, arcing contacts.

• EDM Electrodes: Used for precision machining of hard alloys and dies.

• Heat Sinks: High-power semiconductor packages and microwave devices.

• Resistance Welding Electrodes: Spot and seam welding of non-ferrous metals.

• Aerospace and Military Components: High-temperature structural parts.
