ʻElua kumu nui o ka hana ʻana i nā ferroalloys, ʻo ka hoʻohana ʻana i ke kalapona i hui pū ʻia me nā kaʻina hoʻoheheʻe kūpono, a ʻo ka mea ʻē aʻe ka hoʻemi ʻana i ka metallothermic me nā metala ʻē aʻe. ʻO ke kaʻina hana mua e pili pinepine ana me nā hana pūʻulu, ʻoiai ʻo ka mea hope e hoʻohana nui ʻia e kālele ana i nā alloys kiʻekiʻe kiʻekiʻe i loaʻa ka haʻahaʻa haʻahaʻa.

ʻO ka hoʻoheheʻe metala kahi hana kahiko i koʻikoʻi i ka moʻomeheu kanaka no nā kenekulia. Mai ka hana ʻana i nā kiʻi paʻakikī a hiki i ka hana ʻana i nā indus paʻakikī

ʻO Ferrosilicon kahi ferroalloy koʻikoʻi i hoʻohana nui ʻia i ka metallurgy kila a me ka ʻoihana foundry. E hōʻike piha ana kēia ʻatikala i ke kaʻina hana o ka ferrosilicon, me ke koho ʻana i nā mea maka, nā ʻano hana, ka kahe o ke kaʻina hana, ka mālama ʻana i ka maikaʻi a me ka hopena o ke kaiapuni.

ʻO ka alloy ka hui ʻana a i ʻole ka hopena paʻa i loko o nā metala. Pēlā nō, ʻo ka ferroalloy ka hui ʻana o ka alumini i hui pū ʻia me nā mea ʻē aʻe e like me ka manganese, alum

ʻO ka pauka metala silika he mea koʻikoʻi i ka ʻoihana hana kila. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻohui i ka hana ʻana i nā ʻano kila like ʻole. Me kona mau waiwai kū hoʻokahi a me nā pōmaikaʻi, hana nui ka pauka metala silicon i ka hoʻonui ʻana i ka maikaʻi a me ka hana o nā huahana kila. Ke manaʻo nei kēia ʻatikala e hāʻawi i kahi ʻimi hohonu o ka pauka metala silika no ka hana kila, e hōʻike ana i kona mau hiʻohiʻona, nā noi, a me nā pono e hāʻawi ai i ka ʻoihana kila.

ʻO ka pauka metala silika he mea waiwai nui o ka ʻoihana, hoʻohana nui ʻia i nā semiconductors, ikehu lā, alloys, rubber a me nā māla ʻē aʻe. I nā makahiki i hala iho nei, me ka hoʻomohala wikiwiki ʻana o nā ʻoihana i lalo, ua hōʻike ka mākeke silicon metal powder i kahi ʻano o ka ulu mau.
