Tungsten has been known since prehistoric times, around 350 years ago when Chinese porcelain used peach colored tungsten pigment It was isolated as a novel element by Juan Jose and Fausto Elhuyar in 1783, through charcoal reduction of the oxide which was derived from wolframite (ore of tungsten)
- Tungsten steel - Wikipedia
Tungsten steel (also known as "cemented carbide") 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)
