E pili ana i ka Tungsten Metal
He ʻano metala ka Tungsten. ʻO kona hōʻailona metala ʻo "W"; ʻO kona helu moʻo atomika he 74 a ʻo kona kaumaha atomika he 183.84. He keʻokeʻo, paʻakikī loa a kaumaha. No ka ʻohana chromium a he mau waiwai kemika paʻa. ʻO kāna ʻōnaehana kristal e kū mai ana ma ke ʻano he ʻano kristal cubic i waenakonu o ke kino (BCC). ʻO kona kiko heheʻe ma kahi o 3400 ℃ a ʻoi aku kona kiko paila ma mua o 5000 ℃. ʻO kona kaumaha pili he 19.3. He ʻano metala laha ʻole ia.

【Nā mea ʻē aʻe】ʻO nā mea hao me nā ʻano hoʻohui like ʻole, ʻo ka mea hao tungsten me nā oxides, a me ka mea hao tungsten-molybdenum etc.loaʻa.E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no nā kikoʻī.
He aha ka mea i hoʻohana ʻia ai ke koʻokoʻo tungsten?
ʻO ke koʻokoʻo Tungsten, me ke kiko heheʻe kiʻekiʻe, hoʻohana ʻia ma nā ʻoihana he nui ma muli o ko lākou kūpaʻa wela kiʻekiʻe maikaʻi loa. Hoʻohana ʻia ia no nā filament kukui uila, nā electrodes kukui hoʻokuʻu, nā ʻāpana kukui uila, nā electrodes welding, nā mea hoʻomehana, a pēlā aku.

He aha ka mea e hoʻohana ʻia ai ka pauka tungsten?
Pauka Tungstenhoʻohana ʻia ma ke ʻano he mea maka no ka metala paʻakikī loa, nā huahana metallurgy pauka e like me ke kiko hoʻopili wili a me nā ʻano metala ʻē aʻe. Eia kekahi, ma muli o nā koi koʻikoʻi o kā mākou hui e pili ana i ka hoʻokele maikaʻi, hiki iā mākou ke hāʻawi i ka pauka tungsten maʻemaʻe loa me ka maʻemaʻe ma luna o 99.99%.
