Tungsten-copper alloy is a high-performance composite material that combines the advantages of both tungsten and copper. Tungsten has a melting point as high as 3,410°C and a density of 19.34 g/cm³, while copper has a melting point of 1,080°C and a density of 8.89 g/cm³. Tungsten-copper alloy exhibits excellent performance in high-temperature environments, high strength, and resistance to arc erosion, while also possessing the superior electrical and thermal conductivity of copper. Its composition typically ranges from WCu7 to WCu50, with a uniform microstructure, making it widely used in various high-end industries.

• High Melting Point and High Strength
  The high melting point and high strength of tungsten-copper alloyenable it to perform excellently in high-temperature and high-pressure environments. Whether in the aerospace industry or the nuclear industry, tungsten-copper alloy is capable of handling tasks under extreme conditions.
• Excellent Electrical and Thermal Conductivity
  The presence of copper gives tungsten-copper alloygood electrical and thermal conductivity. This makes it an ideal choice for electrical discharge machining (EDM) electrodes, high-voltage switch electrical alloys,and electronic packaging materials.
• Arc Erosion Resistance
  Tungsten-copper alloyexhibits excellent erosion resistance under high-temperature arc conditions, making it suitable for electrode materials and high-temperatureswitch components.

Copper-tungsten (Cu-W) composite materials have become ideal electrical contact materials in power switching equipment due to their excellent mechanical properties and outstanding arc erosion resistance. However, traditional Cu-W composites with high tungsten content (>50 wt%) exhibit significantly reduced electrical conductivity, poor processability, and high density, which do not align with the development trends of lightweight and compact electrical systems. Therefore, the development of Cu-W composites with low tungsten content while maintaining high electrical and thermal conductivity and improving arc erosion resistance has become a current research focus.

WCu alloy performs stably in high-temperature and high-current environments. Shanghai ZHJ Technologies Co., Ltd. has been in the copper-tungsten alloy products industry for nearly 30 years, specializing in customized global services for electrical contacts. The company can customize electrical contacts of various specifications, properties, dimensions, and grades according to customer requirements.
