Ferrosilicon yog tus neeg sawv cev ntawm ntau yam alloying, siv hauv kev tsim cov hlau thiab cam khwb cia hlau. Qhov sib ntxiv ntawm silicon rau hlau txhim kho tag nrho cov khoom siv hluav taws xob ntawm cov hlau, ua rau nws hnav-tiv taus, ua rau nws cov tawv tawv thiab txhim kho nws cov khoom hluav taws xob. Qhov no ua rau cov txheej txheem alloying yog ib kauj ruam tseem ceeb hauv kev tsim cov hlau tshwj xeeb rau kev lag luam xws li tsheb, aerospace thiab hluav taws xob.
Hauv kev tsim cov hlau cam khwb cia, ferrosilicon kuj tseem siv los txhim kho cov dej ntws thiab cov khoom kawg ntawm cov hlau. Qhov sib ntxiv ntawm ferrosilicon txhawb kev tsim cov graphite thaum lub sij hawm solidification ntawm cam khwb cia hlau, uas yog tsim nyog rau zus tau tej cov grey thiab ductile hlau. Lub xub ntiag ntawm silicon nyob rau hauv lub alloy pab tswj cov duab thiab faib ntawm graphite flakes, ho txhim kho lub machinability, toughness thiab lub zog ntawm lub casting.
