Soft Magnetic Alloy for Shielding sy permalloy core
Soft Magnetic Alloy : dia karazana firaka manana permeability ambony sy faneriterena ambany amin'ny sahan'andriamby malemy.Ity karazana firaka ity dia ampiasaina betsaka amin'ny indostrian'ny radio elektronika, fitaovana fametrahana mazava tsara, fanaraha-maso lavitra ary rafitra fanaraha-maso mandeha ho azy.Ampiasaina amin'ny lafiny roa indrindra izy io: ny fiovan'ny angovo sy ny fanodinana fampahalalana.Fitaovana manan-danja eo amin’ny toekarem-pirenena izany.
