Insimbi ye-silicon iqukethe i-silicon engu-1.0-4.5% kanye nensimbi ye-silicon alloy enokuqukethwe kwekhabhoni engaphansi kuka-0.08% ibizwa nge-silicon steel.
Inezici zokufinyeleleka okuphezulu kazibuthe, ukucindezelwa okuphansi, nokumelana okukhulu, ngakho ukulahlekelwa kwe-hysteresis nokulahlekelwa kwamanje kwe-eddy kuncane.
Isetshenziswa kakhulu njengezinto zikazibuthe kumamotho, ama-transformer, izinto zikagesi nezinsimbi zikagesi.
