I-silicon metal inothile nge-silicon futhi isetshenziswa kakhulu ekwenzeni insimbi, i-casting foundry, ukukhiqizwa kwe-aluminium ingot, ukuhlanzwa nezinye izimboni. Okuqukethwe kwamabanga ahlukene ensimbi ye-silicon kuyahlukahluka futhi ukusetshenziswa kwawo kuhluke kakhulu. Amabanga ajwayelekile ensimbi ye-silicon angama-441, 553, 3303 kanye no-2202, kodwa ngaphezu kwalawa mabanga akhona amabanga angaziwa kangako, afana no-421, 411 kanye no-1101.

Izakhiwo ze-Silicon Metal 411 zifana ne-germanium, i-lead ne-tin. I-silicon, eyesibili kuphela kumoya-mpilo, yayikhona ngesimo se-silicon dioxide noma i-silicate, inothe kakhulu oqweqweni lomhlaba futhi ibalwa ngaphezu kwengxenye yesine yesisindo esiphelele soqweqwe lomhlaba. Isetshenziselwa ikakhulukazi ukukhiqizwa kwe-silicone, izithasiselo ezingenayo i-alloy kanye nokwenza izinto zokuhlanzeka okuphezulu kwe-semiconductor.

I-Silicon Metal 1502  i-silicon metal ikhiqizwa ukusabela kwe-carbothermic ye-silica (i-quartz) esithandweni se-arc sikagesi kusetshenziswa ama-electrode ekhabhoni lapho izinga lokushisa endaweni eyinhloko yokusabela yamazinga okushisa lidlula u-1800ºC.

Ikhwalithi Ephakeme I-Silicon Metal 1501 1502 441 551 insimbi ye-silicon ikhiqizwa ukusabela kwe-carbothermic ye-silica (i-quartz) esithandweni sikagesi se-arc kusetshenziswa ama-electrode ekhabhoni lapho izinga lokushisa endaweni enkulu yokusabela yamazinga okushisa lidlula i-1800ºC.

I-Silicon Metal (i-Si Metal) iyi-silicon ehlanzekile, eyaziwa nangokuthi i-silicon yezimboni noma i-crystalline silicon. Nakuba insimbi ye-silicon ingeyona insimbi, inokucwebezela kwe-metallic ngaphandle. Inezinga eliphezulu lokuncibilika, ukumelana nokushisa okuhle, ukumelana nogesi okuphezulu, kanye nokumelana ne-oxidation ephezulu kakhulu. Isetshenziswa kakhulu njengesithasiselo sama-alloys angewona ayoni futhi iyimpahla eyisisekelo engabalulekile ezimbonini eziningi zobuchwepheshe obuphezulu.

I-BaSi Alloy, kuhlanganise ne-Barium Calcium Silicon kanye ne-Silicon Aluminium Barium Calcium ziwuchungechunge lwama-alloys ayinhlanganisela ngokuyisisekelo akhiwe i-silicon, i-calcium, nensimbi. Zingama-deoxidizers afanelekile ahlanganisiwe kanye nama-desulfurizer okukhiqiza insimbi yezinga eliphezulu, insimbi emnene, insimbi engagqwali, i-nickel alloy, i-titanium alloy kanye nenye ingxubevange ekhethekile. Ifaneleka kahle ekuthuthukisweni kwezinga lokushisa kwe-converter steel smelting.

I-Silicon Calcium isetshenziselwa ukulawula ukuma, usayizi kanye nokusatshalaliswa kwe-oxide ne-sulfide inclusions ukuthuthukisa uketshezi, umshini, i-ductility, kanye nomthelela wezakhiwo zomkhiqizo wensimbi. Ingxubevange iphinde isetshenziselwe ukuguqulwa kokufakwa okungezona ezensimbi.
