Tungsten

Tungsten (W) is an extremely versatile metal that has been adopted at industrial scales in a diverse range of markets. It can be manufactured into metal parts in both pure and alloyed forms. It occurs in the earth’s crust at approximately 0.0064% by weight and is primarily extracted from the ores wolframite and scheelite.

H.C. Starck Solutions has developed a robust line of tungsten products and services, with unparalleled expertise in the field of advanced materials innovation and commercialization.

Properties of Tungsten

Pure tungsten is a transition metal with the highest melting point of all known metallic elements: 3422°C (6192°F). Its boiling point extends even higher, to approximately 5700°C (10,292°F). It has an exceptionally low coefficient of thermal expansion at room temperature of 4.6 mm/m-K combined with high room temperature thermal conductivity of 155 W/m-K.

The density of tungsten is similar to that of gold (Au): 19.3g/cm3. This explains the origin of the metal’s name, which translates literally as ‘heavy stone’.

Tungsten’s Applications and Manufacturing

Tungsten can be manufactured using a range of established production techniques, including:

  • Additive manufacturing
  • Hot and cold rolling
  • Powder Metallurgy
  • Sputtering

When alloyed with additions of nickel, iron and copper, the room temperature mechanical properties and machinability of tungsten are greatly improved.  These advanced manufacturing capabilities have ensured that the enhanced mechanical properties of tungsten and its alloys are available for developers in a range of fields, from aerospace and defense to radiation shielding applications. H.C. Starck Solutions can furnish customers with both pure tungsten and its alloys in a variety of formats. Contact the team to find out more.
