Magnetic shield materials having excellent inner magnetic shield characteristics and an excellent handling strength, method for producing thereof and color picture tubes produced by incorporating the materials are provided. The magnetic shield materials are produced by subjecting hot rolled low carbon steel strips essentially consisting of equal to or less than 0.006 weight % of C, equal to or less than 0.002 weight % of N, equal to or less than 0.5 weight % of Mn, 0.1 - 1.5 weight % of Cu, Fe as a balance and unavoidable impurities to a cold rolling and subsequently annealing the cold rolled steel strips at a temperature of 550 - 850°C.
La présente invention se rapporte à un matériau brut pour écran antimagnétique utilisé dans un tube à image couleur, ayant d'excellentes caractéristiques d'écran antimagnétique interne et une excellente résistance à la manipulation. On fabrique ce matériau en laminant à froid une bande à faible teneur en carbone laminée à chaud, ne contenant pas plus de 0,006 % en poids de carbone, pas plus de 0,002 % en poids d'azote, pas plus de 0,5 % en poids de manganèse, et contenant de 0,1 à 1,5 % en poids de cuivre, le reste étant composé de fer et des impuretés inévitables. Le procédé consiste à recuire ledit matériau entre 550 et 850 DEG C.
