W
73
Tungsten
 
  • Highest melting point among pure metals (3410°C)
  • Low vapor pressure at high melting points
  • Low work function (4.5 eV)
  • High tensile strength and hardness at temperature above 1000°C
  • High thermal conductivity (178 W/m°C (25°C))
  • Low electric resistivity (5.65 μΩcm (27°C))
  • Low thermal expansion coefficient (4.5×10-6/°C (0〜100°C))

Mo
42
Molybdenum
 
  • High melting point (2620°C)
  • High tensile strength at high temperatures
  • High thermal conductivity (140 W/m°C (25°C))
  • Low electric resistivity (5.2 μΩcm (0°C))
  • Low thermal expansion coefficient (5.1×10-6/°C (0〜100°C))
  • Low cost compared to W

Ta
73
Tantalum
 
  • High melting point (2997°C)
  • Low vapor pressure at high temperatures
  • Low work function (4.1 eV)
  • Good corrosion resistance
  • The ductile-brittle transition temperature is lower than room temperature, thus shows good workability at ambient temperature.
  • Thermal conductivity (54 W/m°C (25°C))
  • Low electric resistivity (12.45 μΩ (25°C))
  • Thermal expansion coefficient (6.5×10-6/K (0〜100°C))
