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.

ʻO Ferromolybdenum kahi mea hoʻohui metala amorphous i ke kaʻina hana a he mau waiwai maikaʻi loa i hoʻoili ʻia i nā alloys zinc. ʻO ka pōmaikaʻi nui o ka ferromolybdenum alloy ʻo ia kona paʻakikī paʻakikī, e hana ai i ke kila weldable. ʻO nā hiʻohiʻona o ka ferromolybdenum e hoʻolilo iā ia i kahi papa o ke kiʻi pale ma luna o nā metala ʻē aʻe, e kūpono ai i nā huahana like ʻole.

ʻO Titanium kekahi o nā metala māmā a paʻakikī loa i ʻike ʻia a hiki i kēia manawa, ʻoiai ʻo ke kila kuhili ka hao-carbon. Eia kekahi, ʻoi aku ka maikaʻi o ka titanium alloy ma mua o ke kila kila ma ke ʻano o ka hana. He māmā ke kaumaha a he kiʻekiʻe ka paʻakikī. Ua like kona kū'ē 'ana i ka oxidation ('o ia ho'i, 'o ia ho'i, 'o ka'ōpala) me ke kila kuhili'ole, akā 'oi aku ka pipi'i o ke kumu kū'ai.

ʻO ke kinikona metala 200 mesh he hina hina me ka luster metala. Loaʻa iā ia kahi helu heheʻe kiʻekiʻe, kūpaʻa wela maikaʻi, pale kiʻekiʻe a me ke kūpaʻa oxidation kiʻekiʻe.
