Ferrosilicon ufa ndi ufa wopangidwa ndi zinthu ziwiri, silicon ndi chitsulo, ndipo zigawo zake zazikulu ndi silicon ndi chitsulo.Ferrosilicon ufa ndi zofunika aloyi zakuthupi, amene chimagwiritsidwa ntchito zitsulo, makampani mankhwala, zamagetsi ndi zina.
Zigawo zazikulu za ufa wa ferrosilicon ndi silicon ndi chitsulo, zomwe zili mu silicon nthawi zambiri zimakhala pakati pa 50% ndi 70%, ndipo chitsulo chimakhala pakati pa 20% ndi 30%.Ferrosilicon ufa ulinso pang'ono aluminium, calcium, magnesium ndi zinthu zina.Mankhwala a ferrosilicon ufa ndi okhazikika, osati oxidize, ndipo amatha kusungidwa kwa nthawi yaitali.Maonekedwe a ferrosilicon ufa ndiabwino kwambiri, okhazikika kutentha, mphamvu yayikulu, kuuma kwambiri komanso kukana kuvala kwambiri.
