Tungsten, ama wolfram, waa curiye kiimiko ah oo leh calaamad W iyo lambarka atomiga 74. Magaca tungsten wuxuu ka yimid magacii hore ee Iswidishka ee tungstate macdanta scheelite, tung sten ama "dhagaxa culus".Tungsten waa bir dhif ah oo si dabiici ah looga helo dhulka ku dhawaad si gaar ah loogu daro walxo kale oo ku jira xeryahooda kiimikada halkii ay ka ahaan lahaayeen kali.Waxaa loo aqoonsaday inuu yahay curiye cusub 1781 waxaana markii ugu horreysay loo go'doomiyay bir ahaan 1783. Waa macdano muhiim ah oo ay ka mid yihiin wolframite iyo scheelite.
Cunsurka xorta ah waa mid cajiib ah xooggiisa, gaar ahaan xaqiiqda ah in uu leeyahay meesha ugu sareysa ee dhammaan walxaha la helay, oo dhalaalay 3422 ° C (6192 ° F, 3695 K).Waxa kale oo ay leedahay barta karkarinta ugu sareysa, at 5930 °C (10706 °F, 6203 K).Cufnaantiisu waa 19.3 jeer biyaha, marka loo barbar dhigo kan Yuraaniyaamka iyo dahabka, aadna uga sarreeya (qiyaastii 1.7 jeer) kan macdanta rasaasta ah.Polycrystalline tungsten waa shay si hoose u jajaban oo adag (marka la eego shuruudaha caadiga ah, marka aan la isku darin), taas oo adkeyneysa in la shaqeeyo.Si kastaba ha ahaatee, tungsten-ka-crystalline saafi ah ayaa aad u sii qulqulaya waxaana lagu gooyn karaa hacksaw bir adag ah.
Alloysyada badan ee Tungsten waxay leeyihiin codsiyo badan, oo ay ku jiraan fiilooyinka guluubka iftiinka, tuubooyinka raajada (sida filaha iyo bartilmaameedka labadaba), korantada alxanka tungsten gaaska, superalloys, iyo gaashaanka shucaaca.Adaygnimada Tungsten iyo cufnaanta sare waxay siinaysaa codsiyo milatari oo gudaha ah.Xeryahooda Tungsten ayaa sidoo kale inta badan loo isticmaalaa kicinta warshadaha.
Tungsten waa birta kaliya ee ka timid taxanaha kala guurka saddexaad ee la og yahay inay ku dhacaan biomolecules kuwaas oo laga helo noocyo dhowr ah oo bakteeriyada iyo archaea ah.Waa cunsurka ugu culus ee la og yahay inuu lama huraanka u yahay noole kasta.Si kastaba ha ahaatee, tungsten waxay faragelisaa molybdenum iyo dheef-shiid kiimikaad ah waxayna xoogaa sun ah u tahay noocyada caanka ah ee nolosha xayawaanka.
