ʻO nā ʻano hana hana Ferro-tungsten ka ʻano agglomeration, ke ʻano o ka hao a me ke ʻano wela alumini.

ʻO ka uea kalapona silicate cored (CaSi Cored Wire) he ʻano uea cored i hoʻohana ʻia i ka hana kila a me ka hoʻolei ʻana. Hoʻolālā ʻia e hoʻokomo i ka nui o ka calcium a me ke silika i loko o ke kila hoʻoheheʻe e kōkua i ka deoxidation, desulphurization a me ka hoʻohuihui. Ma ka hoʻolaha ʻana i kēia mau hopena koʻikoʻi, hoʻomaikaʻi ka uea cored i ka maikaʻi, ka maʻemaʻe a me nā waiwai mechanical o ke kila.

ʻO Vanadium kahi mea hoʻohui nui i hoʻohana nui ʻia i ka ʻoihana kila. Loaʻa nā waiwai maikaʻi o Vanadium e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa maikaʻi ʻana, no laila ua hoʻohana nui ʻia i nā mīkini, nā kaʻa, ka hana moku, nā alahao, nā mokulele, nā alahaka, nā ʻenehana uila, nā ʻoihana pale a me nā ʻoihana ʻē aʻe.

ʻO nā ʻano hana o ka haʻahaʻa haʻahaʻa a me ka medium carbon ferromanganese ka nui o ka electrosilicon thermal method, rocker method and oxygen blowing method.

Hana ʻia ka carbide silika ʻeleʻele mai ke one quartz a me ka petroleum coke silica ma ke ʻano he kumu kumu ma o ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe i loko o kahi umu kūʻē. ʻO kona paʻakikī ma waena o ka corundum a me ke daimana, ʻoi aku ka kiʻekiʻe o kona ikaika mechanical ma mua o ka corundum, a he palupalu a ʻoi. Hana ʻia ʻo Green silicon carbide mai ka petroleum coke a me ka silica ma ke ʻano he kumu nui, me ka paʻakai i hoʻohui ʻia ma ke ʻano he additive, a hoʻoheheʻe ʻia i ka wela kiʻekiʻe i loko o kahi umu kūʻē. Aia kona paʻakikī ma waena o ka corundum a me ke daimana, a ʻoi aku kona ikaika mechanical ma mua o ka corundum.

ʻO Ferromolybdenum kahi huila o ka molybdenum a me ka hao a hoʻohana nui ʻia ma ke ʻano he molybdenum additive i ka hana kila. ʻO ka hoʻohui ʻana i ka molybdenum i ke kila hiki ke hoʻolilo i ke kila i kahi ʻano like ʻole o ke kila, hiki ke kōkua i ka hoʻopau ʻana i ka brittleness a hoʻomaikaʻi i ka paʻakikī o ke kila. I ke kila kiʻekiʻe, hiki i ka molybdenum ke pani i kahi ʻāpana o ka tungsten. Me nā mea hoʻohui'ē aʻe, hoʻohana nuiʻia ka molybdenum i ka hanaʻana i nā kila wela, nā kila kila, nā meaʻawaʻawa a me nā mea hana, a me nā'āpana me nā mea kino kūikawā. Hiki i ka hoʻohui ʻana i ka molybdenum i ka hao ke hoʻonui i kona ikaika a me ke kūpaʻa. Hoʻohehe pinepine ʻia ka Ferromolybdenum e ke ʻano wela metala.
