Applications:
Copper Tungsten alloys are used where the combination of high heat resistance, high electrical and thermal conductivity, and low thermal expansion are needed.
Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks.
Used extensively in engineering, electrical and electron industries as well as in metallurgy and in aviation.
Combining advantageous attributes of high conductivity of copper and low expansive property of tungsten, it is highly suitable for use in dense circuits and high voltage electrical devices, heat sinks, electrical contacts and electrodes.
Widely used in chip carriers, substrates and frames for power and semiconductor devices.
1.Tungsten copper is widely used in many industrial areas such as aerospace, power, electronic, metallurgy, and machinery;
2.It is also used for cooling device in electronic equipment;
3.Tungsten copper is also adopted as electrodes in resistance welding machine;
4.Arcing contacts and vacuum contacts in high and medium voltage breakers or vacuum interrupters adopt it as material;
5.It is adopted as passive cooling element in heat sink for electronic devices and electronic packaging materials;
6.Tungsten copper can be used as the component of the pushing device in spacecrafts.
