摘要： An aperture grill material for a color picture tube having excellent tensile strength and high-temperature creep characteristics and magnetic characteristics superior to existing materials, a production method therefor, an aperture grill and a color picture tube. The aperture grill material for a color picture tube is characterized by being consisting of a low-carbon alloy steel sheet containing 0.05 to 2.5% by weight of Cu and 0.001 to 0.4% by weight of P, and containing 0.01 to 0.5% by weight of at least one of at least one of Cr and Mo. A production method for the aperture grill material for a color picture is characterized by comprising the steps of cold-rolling a low-carbon alloy hot-rolled steel strip containing 0.05 to 2.5% by weight of Cu, 0.001 to 0.4% by weight of P, and 0.01 to 0.5% by weight of at least one of Cr and Mo, and then precipitating the steel strip within a temperature range 300 to 800° C.
