ʻO ka Molybdenum a me ka tungsten nā metala refractory me nā helu heheʻe kiʻekiʻe a me nā waiwai mechanical a me nā thermal maikaʻi, akā he mau ʻokoʻa ko lākou:

1. Heʻoi aku ka nui o ka helu heheʻe o ka tungsten ma mua o ka molybdenum. ʻO Tungsten ka helu hoʻoheheʻe kiʻekiʻe loa ma 3422 ° C, aʻo ka molybdenum kahi helu heheʻe o 2623 ° C.

2. Density: ʻOi aku ka paʻakikī o Tungsten ma mua o ka molybdenum. He 19.25 g/cm3 ka nui o ka Tungsten, a he 10.28 g/cm3 ka molybdenum.

3. Nā waiwai mīkini: ʻoi aku ka paʻakikī o ka Tungsten ma mua o ka molybdenum. Hoʻohana maʻamau ʻia ʻo Tungsten i nā noi kahi koʻikoʻi ka paʻakikī a me ke kūpaʻa ʻana, e like me nā mea hana ʻoki a me nā ʻāpana umu wela kiʻekiʻe. ʻO Molybdenum, ma kekahi ʻaoʻao, ʻoi aku ka ductile a hoʻohana pinepine ʻia i nā noi i mea nui ka paʻakikī a me ka maʻalahi.

4. Nā noi: Ma muli o kona wahi hoʻoheheʻe kiʻekiʻe a me ka paʻakikī, hoʻohana mau ʻia ka tungsten i nā noi wela kiʻekiʻe e like me ka ʻoihana aerospace, nā mea pili uila, a me ke ʻano o nā filaments kukui. Hoʻohana ʻia ʻo Molybdenum i nā noi wela kiʻekiʻe, akā koho maʻamau no kona hiki ke kū i ka haʻalulu wela a me kāna conductivity thermal maikaʻi loa.

I ka hōʻuluʻulu ʻana, ʻoiai ʻo ka molybdenum a me ka tungsten nā mea waiwai ʻelua me nā waiwai like, ʻo kā lākou ʻokoʻa i ka helu heheʻe, ka nui, nā waiwai mechanical a me nā noi e kūpono iā lākou no nā hoʻohana ʻenehana a me nā ʻenehana.
