Abstract
Magnetic sheet metal obtained from hot-rolled strip steel containing, in particular, iron, silicon and aluminium and forming part of a family of sheet metals having orientated grains, characterized in that its composition is as follows: silicon less than 3.3%, aluminium between 1.5 and 8%, in concentration by weight, and in that the strip steel is subjected to cold-rolling in two steps with a final degree of reduction of between 50 and 80%, the magnetic sheet metal obtained having a general structure of the cubic type, at least 40% of the grains not deviating by more than 15.degree. from the ideal cubic orientation (100), 001 in the Miller notation.
