Ko te Tungsten, he wolfram rānei, he huānga matū kei te tohu W me te nama ngota 74. Ko te ingoa tungsten i ahu mai i te ingoa o mua o Huitene mō te kohuke tungstate scheelite, tung sten, "kohatu taumaha" rānei. He konganuku onge te Tungsten e kitea ana i runga i te Ao, tata tonu ki te whakakotahi me ētahi atu huānga i roto i ngā matū matū, kaua ko ia anake. I tautuhia hei huānga hou i te tau 1781, ā, i wehea tuatahitia hei konganuku i te tau 1783. Ko ōna konganuku nui ko te wolframite me te scheelite.
He mea whakamiharo te huānga kore utu mō tōna pakari, inā koa ko tōna ira rewa teitei rawa atu o ngā huānga katoa i kitea, e rewa ana i te 3422 °C (6192 °F, 3695 K). Ko tōna ira kohua teitei rawa atu hoki, i te 5930 °C (10706 °F, 6203 K). Ko tōna mātotoru he 19.3 ngā wā i te wai, he rite ki te uranium me te koura, ā, he nui ake (tata ki te 1.7 ngā wā) i te mata. He rauemi pakarukaru, he uaua hoki te tungsten polycrystalline (i raro i ngā āhuatanga paerewa, ina kore e honoa), he uaua ki te mahi. Heoi, he ngāwari ake te tungsten kotahi-crystalline parakore, ā, ka taea te tapahi ki te kani maitai mārō.
He maha ngā whakamahinga o ngā koranu maha o te Tungsten, tae atu ki ngā miro rama kanapa, ngā ngongo hihi-X (hei miro me te ūnga), ngā irahiko i roto i te whakarewa pewa tungsten hau, ngā koranu tino pai, me te ārai irahiko. Nā te pakeke me te matotoru o te tungsten ka whakamahia hei hōia i roto i ngā pere wero. He maha hoki ngā whakamahinga o ngā matū tungsten hei whakakorikori ahumahi.
Ko te tungsten anake te konganuku mai i te tuatoru o ngā raupapa whakawhiti e mōhiotia ana kei roto i ngā koiora koiora e kitea ana i roto i ētahi momo huakita me ngā archaea. Koinei te huānga taumaha rawa atu e mōhiotia ana he mea nui ki tētahi mea ora. Heoi, ka whakararu te tungsten i te pākia o te molybdenum me te parahi, ā, he ahua paitini ki ngā momo kararehe e mōhiotia whānuitia ana.
