Abstract

A method for manufacturing a strip in a soft magnetic alloy capable of being cut out mechanically, the chemical composition of which comprises by weight: The remainder being iron and impurities resulting from the elaboration, according to which a strip obtained by hot rolling is cold-rolled in order to obtain a cold-rolled strip with a thickness of less than 0.6 mm. After cold rolling, a continuous annealing treatment is carried out by passing into a continuous oven, at a temperature comprised between the order/disorder transition temperature of the alloy and the onset temperature of ferritic/austenitic transformation of the alloy, followed by rapid cooling down to a temperature below 200° C. Strip obtained.
