Legend

Name origin:	Swedish: tung sten (heavy stone): symbol from its German name wolfram.
Description:	Hard, steel-gray to white metal. Highest melting point of all metals.
Discovered by:	Fausto and Juan José de Elhuyar
Year:	1783
Place:	Spain
Sources:	Occurs in the minerals scheelite (CaWO4) and wolframite [(Fe,Mn)WO4].
Use(s):	Made into filaments for vacuum tubes and electric lights. Also as contact points in cars. Combined with calcium or magnesium it makes phosphors. Tungsten carbide is extremely hard and is used for making cutting tools and abrasives.
