Abstract

The object of the present invention is to provide a material for an aperture grille for use in a color picture tube, which has an excellent yield strength and high temperature creep strength and superior magnetic characteristics to currently used materials. The other objects are to provide a producing method of the above mentioned material for an aperture grille, and to provide an aperture grille made thereof and a color picture tube incorporating the aperture grille. The method comprises the steps of cold-rolling a low carbon steel sheet containing 0.05 to 2.5 wtpercent of Cu, or 0.5 to 2.5 wtpercent of Cu and 0.001to 0.4 wtpercent of P, and subjecting same to ageing at a temperature of 300 to 700 degree C. Alternatevely, the method comprises the steps of: cold-rolling the low carbon steel sheet same as mentioned above, and subjecting same to process-annealing at a temperature of 500 to 800 degree C.then another cold-rolling, and ageing thereafter.
