ʻO Tungsten, a i ʻole wolfram, he mea kemika me ka hōʻailona W a me ka helu atomic 74. ʻO ka inoa tungsten mai ka inoa Suedena mua no ka tungstate mineral scheelite, tung sten a i ʻole "pōhaku kaumaha".ʻO Tungsten kahi metala kakaʻikahi i loaʻa maoli ma ka Honua kokoke i hui pū ʻia me nā mea ʻē aʻe i loko o nā pūhui kemika ma mua o ka hoʻokahi.Ua ʻike ʻia he mea hou i ka makahiki 1781 a ua hoʻokaʻawale mua ʻia ma ke ʻano he metala i ka makahiki 1783. ʻO nā ores koʻikoʻi ka wolframite a me ka scheelite.

He mea kupaianaha ka mea manuahi no kona ikaika, ʻoi aku ka nui o ka helu heheʻe o nā mea a pau i ʻike ʻia, hehee ma 3422 °C (6192 °F, 3695 K).Loaʻa iā ia ka helu hoʻolapalapa kiʻekiʻe loa, ma 5930 °C (10706 °F, 6203 K).ʻO kona mānoanoa he 19.3 manawa o ka wai, e like me ka uranium a me ke gula, a ʻoi aku ka kiʻekiʻe (ma kahi o 1.7 mau manawa) ma mua o ko ke kēpau.ʻO ka polycrystalline tungsten he mea palupalu a paʻakikī (ma lalo o nā kūlana maʻamau, ke hoʻohui ʻole ʻia), he mea paʻakikī ke hana.Eia naʻe, ʻoi aku ka ductile maʻemaʻe hoʻokahi-crystalline tungsten a hiki ke ʻoki ʻia me kahi hacksaw paʻakikī.

He nui nā hoʻohana ʻana o nā huila he nui o Tungsten, ʻo ia hoʻi nā filaments kukui kukui, nā paipu X-ray (ʻo ia ka filament a me ka pahuhopu), nā electrodes i ka welding arc tungsten gas, superalloys, a me ka pale radiation.ʻO ka paʻakikī o Tungsten a me ke kiʻekiʻe kiʻekiʻe e hāʻawi iā ia i nā noi koa i nā projectiles komo.Hoʻohana pinepine ʻia nā pūhui Tungsten e like me nā catalysts ʻoihana.

ʻO Tungsten wale nō ka metala mai ke kolu o ka moʻo hoʻololi i ʻike ʻia i loko o nā biomolecules i loaʻa i loko o kekahi mau ʻano bacteria a me archaea.ʻO ia ka mea kaumaha loa i ʻike ʻia he mea nui i kēlā me kēia mea ola.Eia naʻe, keʻakeʻa nei ka tungsten i ka molybdenum a me ka metabolism keleawe a he mea ʻawaʻawa ia i nā ʻano ola holoholona.
