Ferrosilicon wani muhimmin gami ne da ake amfani da shi wajen samar da karfe da sauran karafa. Ya ƙunshi baƙin ƙarfe da silicon, tare da nau'ikan abubuwa daban-daban kamar su manganese da carbon. Tsarin masana'anta na ferrosilicon ya haɗa da rage ma'adini (silicon dioxide) tare da coke (carbon) a gaban ƙarfe. Wannan tsari yana buƙatar yanayin zafi mai yawa kuma yana da ƙarfin kuzari, yana sa farashin albarkatun ƙasa ya zama muhimmiyar mahimmanci wajen ƙayyade ƙimar masana'anta gabaɗaya na ferrosilicon.

Ferrosilicon ne yadu amfani a karfe masana'antu, kafa masana'antu da sauran masana'antu samar. Suna cinye fiye da 90% na ferrosilicon. Daga cikin nau'o'i daban-daban na ferrosilicon, 75% ferrosilicon shine mafi yawan amfani. A cikin masana'antar ƙarfe, kusan 3-5kg 75% ferrosilicon ana cinyewa ga kowane tan na ƙarfe da aka samar.

Ferrosilicon nitride da silicon nitride suna kama da samfuran kamanni biyu, amma a zahiri, sun bambanta. Wannan labarin zai bayyana bambanci tsakanin su biyu daga kusurwoyi daban-daban.

Ferromolybdenum wani ferroalloy ne wanda ya ƙunshi ƙarfe da molybdenum. Ana samar da shi ta hanyar narke cakuda molybdenum maida hankali da baƙin ƙarfe a cikin tanderu. Ferromolybdenum wani nau'i ne mai mahimmanci wanda za'a iya amfani dashi a aikace-aikace iri-iri a cikin masana'antu daban-daban.

Tungsten-iron Alloys yawanci suna nufin gami da suka ƙunshi tungsten (W) da baƙin ƙarfe (Fe). Gabaɗaya magana, tungsten-iron alloys ba maganadisu ba ne. Wannan saboda tungsten kanta ba ƙarfe ba ne, kuma abun cikin baƙin ƙarfe a cikin alluran tungsten-iron galibi yana da ƙasa, wanda ba zai iya ba da gaɗaɗɗen magnetism mai mahimmanci ba.

Titanium ba maganadisu ba ne. Wannan saboda titanium yana da tsarin crystal wanda ba shi da nau'ikan lantarki waɗanda ba a haɗa su ba, waɗanda ke da mahimmanci don abu don nuna maganadisu. Wannan yana nufin cewa titanium baya mu'amala da filayen maganadisu kuma ana ɗaukarsa a matsayin abu na diamagnetic.
