Silicon uamea o loʻo i ai le 1.0-4.5% silicon ma silicon alloy steel ma le carbon content of less than 0.08% ua taʻua o le silicon steel.
E i ai uiga o le maualuga maneta permeability, coercivity maualalo, ma resistivity tele, o lea e laiti hysteresis gau ma eddy i le taimi nei gau.
E masani ona faʻaaogaina e pei o mea maneta i afi, transformers, mea eletise ma mea eletise.
