Hoʻohana ʻia ʻo Tungsten i nā umu no nā kumu he nui:

1. Kiekie hehee ai: Tungsten he kiʻekiʻe loa o 3,422 degere Celsius (6,192 degere Fahrenheit), kekahi o ka kiekie loa hehee ai o nā metala a pau. Hana kēia i ka tungsten i mea kūpono no nā ʻāpana umu e pili ana i nā wela kiʻekiʻe loa, e like me nā mea wela a me nā crucibles.

2. Paʻa wela: Hōʻike ka Tungsten i ke kūpaʻa wela maikaʻi loa ma nā wela kiʻekiʻe. Hāʻawi kēia waiwai i nā ʻāpana tungsten e kū i nā wela kiʻekiʻe i hana ʻia i loko o nā umu me ka ʻole o ka deformation a i ʻole degradation, e hōʻoia ana i ka hilinaʻi lōʻihi a me ka hana.

3. Thermal conductivity: He kiʻekiʻe ka wela o ka Tungsten a hiki ke hoʻokō pono i ka hoʻoili wela i loko o ka umu. Hāʻawi kēia waiwai i ka hoʻomehana like ʻana a me ka hāʻawi ʻana i ka mahana, he mea koʻikoʻi no nā ʻano hana wela kiʻekiʻe e like me ka hoʻoheheʻe metala, sintering a me ka mālama wela.

4. Kū'ē kū'ē: Kū'ē nui ka Tungsten i ka hoʻouka kemika a me ka oxidation i nā wela kiʻekiʻe, e kūpono ana ia no ka hoʻohanaʻana i nā kapuahi umu ahi e hoʻohaʻahaʻa ai i nā mea'ē aʻe me ka lewa a puni.

ʻO ka holoʻokoʻa, ʻo ka helu heheʻe kiʻekiʻe o ka tungsten, ke kūpaʻa wela, ka conductivity thermal, a me ka pale ʻana i ka corrosion he koho maikaʻi loa ia no nā ʻāpana umu, ʻoi loa i nā noi e pili ana i ka wela wela a me nā kūlana hana paʻakikī.
