    The discovery of superhard tungsten tetraboride is further evidence for the promising design approach of covalently bonding incompressible transition metals with boron. While WB 4 was first synthesized and identified as the highest boride of tungsten in 1966, [52] it was only recognized as an inexpensive superhard material in 2011. [53]

    en.wikipedia.org/wiki/Refractory_metals

    For the production of the tungsten heavy alloy, binder mixtures of nickel and iron or nickel and copper are widely used. The tungsten content of the alloy is normally above 90%. The diffusion of the binder elements into the tungsten grains is low even at the sintering temperatures and therefore the interior of the grains are pure tungsten. [18]

    Unobtanium is able to convert heat and pressure into energy that reinforces its own structure, allowing the construction of a vessel capable of enduring a trip to the Earth's core. In addition, it can also turn heat into electric power. Unobtanium is created by combining unspecified crystals in a tungsten-titanium matrix at very low temperatures.

  9. Tungsten steel - Wikipedia

    en.wikipedia.org/wiki/Tungsten_steel

    Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...
