Tungsten Applications

Tungsten is employed in filaments in incandescent light bulbs electric contacts and arc-welding electrodes. Tungsten is also used in alloys, like steel, to which it imparts great strength. Cement carbide is the most vital use for tungsten. It's the strength of forged iron, and it makes excellent cutting tools for the machining of steel. Tungsten is additionally utilized in microchip technology and liquid crystal displays.

Tungsten Main Characteristics

  • High melting point (3420°C)
  • Low thermal expansion (4.5 x 10-6/K)
  • High electrical resistance (5.5 µΩ/cm at 20°C)
  • Low vapor pressure (1650°C, 3000°C)
  • Good thermal conductivity (129 W/m x K at 20°C)
  • High density (19.25 g/cm³)

Tungsten Electrical Properties

  • Electrical Resistivity: 5.5 μΩ/cm at 20°C
  • Temperature Coefficient of the Electrical Resistivity: 0.00482 Ω/ΩK
  • Temperature of Superconductivity: 0.016 K

Tungsten Chemical Properties

Tungsten is resistant to corrosion when the humidity is below 60%. However, it must be protected at elevated temperatures. Tungsten can oxidize in the presence of oxidizing gases at temperatures above 250°C. Despite this vulnerability, molten glass, nitrogen, inert gases, molten metals, and ceramic oxides only slightly affect it.

Tungsten Thermal Properties

  • Melting Point: 3410°C (+ 20°C)
  • Boiling Point: 5555°C
  • Specific Heat: 0.14 kJ/kg x K at 20°C
  • Latent Heat of Fusion: 209 kJ/kg (estimated)
  • Thermal Conductivity: 129 W/m x K at 20°C
  • Evaporation Heat: 444 J/g

Tungsten Mechanical Properties

A lot of factors such as microstructure, impurity contents in the tungsten, other alloying elements, and heat treatment (for example annealing conditions) influence the mechanical properties of tungsten. By offering various tungsten alloys, we could satisfy the specific needs of customers.
