Tungsten Copper Alloy (Copper Tungsten, CuW, or WCu) is a composite metal of copper and tungsten which possessed many excellent characteristic of tungsten and copper. The alloy combines the properties of both metals, and melting point of tungsten is high(melting point of tungsten is 3410℃, and copper is 1083℃), density is big(density of tungsten is 19.34g/cm3, copper is 8.92g/cm3); electric conductivity and heat-conducting property is great for copper. Microstructure of tungsten copper alloy (normal range of composition is WCu10~WCu50) is well-distributed resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine. Therefore, tungsten copper alloy are widely used in military heat resistance material, electrician alloy used in HV switch, electromachining electrode, microelectronic material, and acted as parts and components popular used in fields of aerospace, aviation, electronic, electric power, metallurgy, machinery, sport equipment etc.. 

Application:

1. WCu alloys are widely used in many industrial areas such as aerospace, power, electronic, metallurgy, and machinery.

2. WCu alloys are also used as heat sinks for cooling device in electronic equipment and electronic packaging materials.

3. WCu alloys are adopted as electrodes for resistance welding.

4. WCu alloys can be used as the component of the pushing device in spacecrafts.

5. WCu alloys can be used for producing arcing contacts and vacuum contacts in high and medium voltage breakers.
