The invention relates to a soft magnetic iron-nickel material containing 46-49% nickel, the residue being substantially iron. The characterizing feature of the invention is that after a heat treatment on a strip sample 0.20 mm in thickness, the iron-nickel material has a texture distribution in which of measured (111) polar figures the relative proportions of the texture components having the Euler angles (?1, .PHI., ?2) = (0, 0, 0) are 20 to 50% and (?1, .PHI., ?2) = (26, 45, 30) are 10 to 40%, or having the Euler angles (?1, .PHI., ?2) = (0, 0, 0) are 10 to 40%, (?1, .PHI., ?2) = (26, 45, 30) are 5 to 25% and (?1, .PHI., ?2) = (30, 35, 35) are 10 to 25%.
L'invention porte sur un matériau fer-nickel à propriétés magnétiques de faible intensité contenant 46 à 49 % de nickel, le reste étant essentiellement du fer. L'invention est caractérisée en ce qu'après un traitement thermique sur une bande d'échantillonnage ayant une épaisseur de 0,20 mm, le matériau fer-nickel a une distribution de texture dans laquelle une polaire (111) mesurée représente les proportions relatives des composantes de texture dont les angles d'Euler (?1, .PHI., ?2) = (0, 0, 0) sont compris entre 20 et 50 % et (?1, .PHI., ?2) = (26, 45, 30) entre 10 et 40 %, ou dont les angles d'Euler (?1, .PHI., ?2) = (0, 0, 0) sont compris entre 10 et 40 %, (?1, .PHI., ?2) = (26, 45, 30) entre 5 et 25 % et (?1, .PHI., ?2) = (30, 35, 35) entre 10 et 25 %.
