Tungsten, kapa wolfram, ke ntho ea lik'hemik'hale e nang le letšoao la W le nomoro ea athomo ea 74. Lebitso la tungsten le tsoa lebitsong la pele la Seswedishe bakeng sa tungstate mineral scheelite, tung sten kapa "heavy stone". Tungsten ke tšepe e fumanehang seoelo e fumanehang ka tlhaho Lefatšeng e batlang e kopantsoe ka mokhoa o ikhethileng le likarolo tse ling tsa metsoako ea lik'hemik'hale eseng feela. E ile ea tsejoa e le ntho e ncha ka 1781 'me ea qala ho aroloa e le tšepe ka 1783. Li-ores tsa bohlokoa li kenyelletsa wolframite le scheelite.
Ntho e sa lefelloeng e tsoteha ka lebaka la ho tiea ha eona, haholo-holo taba ea hore e na le sebaka se phahameng ka ho fetisisa sa ho qhibiliha ho feta likarolo tsohle tse sibolotsoeng, e qhibiliha ho 3422 °C (6192 °F, 3695 K). E boetse e na le sebaka se belang se phahameng ka ho fetisisa, ho 5930 °C (10706 °F, 6203 K). Boima ba eona bo mena ka makhetlo a 19,3 ho feta ba metsi, ha bo bapisoa le ba uranium le khauta, ’me bo phahame haholo (ka makhetlo a ka bang 1,7) ho feta ba loto. Polycrystalline tungsten ke thepa e brittle le e thata (tlas'a maemo a tloaelehileng, ha e sa kopane), e etsang hore ho be thata ho sebetsa. Leha ho le joalo, tungsten e hloekileng ea single-crystalline e na le ductile e ngata 'me e ka sehoa ka hacksaw ea tšepe e thata.
Li-alloys tse ngata tsa Tungsten li na le lits'ebetso tse ngata, ho kenyeletsoa likhoele tsa lebone la lebone la incandescent, li-tubes tsa X-ray (e le li-filament le sepheo), li-electrode tse ka har'a li-welding tsa gas tungsten arc, superalloys, le ts'ireletso ea mahlaseli. Ho thatafala ha Tungsten le letsoalo le phahameng li fana ka ts'ebeliso ea sesole ho li-projectiles tse phunyeletsang. Lik'hemik'hale tsa Tungsten le tsona li sebelisoa hangata joalo ka li-catalyst tsa indasteri.
Tungsten ke eona feela tšepe e tsoang lethathamong la boraro la phetoho e tsejoang hore e etsahala ho li-biomolecules tse fumanehang mefuteng e seng mekae ea libaktheria le archaea. Ke ntho e boima ka ho fetisisa e tsejoang e le ea bohlokoa ho ntho leha e le efe e phelang. Leha ho le joalo, tungsten e sitisa metabolism ea molybdenum le koporo ’me e batla e le chefo mefuteng e tloaelehileng ea bophelo ba liphoofolo.
