COPPER TUNGSTEN (CuW) Copper, Brass, Bronze Steel Product

  • Cu25W75


Typical Chemical Composition:

  • W: 75%
  • Cu: 25%


Typical Mechanical Properties:

  • Hardness: 94-96 HRB / 210 HV
  • Melting Point: 3410oC (Tungsten) 1083oC (Copper)
  • Boiling Point: 5660oC (tungsten) 2595oC (Copper)
  • Bending Strength: min 885 MPA
  • Electrical Conductivity: min 42% IACS



  • 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.


Profiles Available:
