Abstract

The object of the present invention is to provide a material for aperture grille for use in color picture tubes, which has excellent yield strength and high temperature creep strength and superior magnetic characteristics to currently used materials. The other objects are to provide a method to use the above mentioned material for the production of 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 wt% of Cu, or 0.5 to 2.5 wt% of Cu and 0.001 to 0.4 wt% of P, and subjecting same to ageing at a temperature of 300 to 700 DEG C. Alternatively, 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 DEG C, then another cold-rolling, and aging thereafter.
