ʻO Tungsten, a i ʻole wolfram, he mea kemika me ka hōʻailona W a me ka helu atomika 74. Loaʻa ka inoa tungsten mai ka inoa Suedena mua no ka mineral tungstate scheelite, tung sten a i ʻole "pōhaku kaumaha". He metala kakaikahi ʻo Tungsten i loaʻa maoli ma ka Honua i hui pū ʻia me nā mea ʻē aʻe i loko o nā hui kemika ma mua o ka hoʻokahi. Ua ʻike ʻia ʻo ia he mea hou i ka makahiki 1781 a ua hoʻokaʻawale mua ʻia ʻo ia he metala i ka makahiki 1783. ʻO kāna mau ores koʻikoʻi e komo pū me ka wolframite a me ka scheelite.

He mea kupaianaha ka mea manuahi no kona paʻa, ʻoiai ʻo ia ka mea i loaʻa iā ia ke kiko heheʻe kiʻekiʻe loa o nā mea āpau i ʻike ʻia, e heheʻe ana ma 3422 °C (6192 °F, 3695 K). Loaʻa iā ia ke kiko paila kiʻekiʻe loa, ma 5930 °C (10706 °F, 6203 K). ʻO kona nui he 19.3 manawa o ka wai, e like me ka uranium a me ke gula, a ʻoi aku ke kiʻekiʻe (ma kahi o 1.7 manawa) ma mua o ke kēpau. He mea palupalu a paʻakikī ka tungsten polycrystalline (ma lalo o nā kūlana maʻamau, ke hui ʻole ʻia), e paʻakikī ai ka hana. Eia nō naʻe, ʻoi aku ka ductile o ka tungsten crystalline hoʻokahi maʻemaʻe a hiki ke ʻoki ʻia me kahi hacksaw kila paʻakikī.

He nui nā noi o nā mea hoʻohuihui o Tungsten, me nā filament kukui incandescent, nā paipu X-ray (e like me ke filament a me ka pahuhopu), nā electrodes i loko o ka wili ʻana o ke kinoea tungsten arc, nā superalloys, a me ka pale ʻana i ka radiation. ʻO ka paʻakikī o Tungsten a me ke kiʻekiʻe o ka density e hāʻawi iā ia i nā noi koa i nā projectiles penetrating. Hoʻohana pinepine ʻia nā hui Tungsten ma ke ʻano he catalysts ʻoihana.

ʻO Tungsten wale nō ka metala mai ke kolu o ka moʻo hoʻololi i ʻike ʻia e kū mai ana 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 kekahi meaola ola. Eia nō naʻe, hoʻopilikia ka tungsten i ka metabolism o ka molybdenum a me ke keleawe a he mea ʻawahia iki i nā ʻano holoholona maʻamau.
