Copper Tungsten (CuW)

  • Cu25W75
  • 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 its applications are electric resistance welding, electrical contacts, as well 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.
