Abstract

Matière magnétique à base d'aluminium, de silicium, de nobium et de fer. Elle contient, en poids, 3 à 8 % d'aluminium, 4 à 8 % de silicium, 0,1 à 2 % de niobium ou de tantale ou d'une combinaison des deux, 0,5 à 7 % d'une combinaison de vanadium et de cuivre, le reste en fer. On obtient ainsi une augmentation de la perméabilité du matériau. Applications : fabrication de têtes magnétiques.
