A method of efficiently producing an Fe-Ni alloy material for shadow masks capable of minimizing uneven streaks occurring at piercing by etching, Fe-Ni alloy material for shadow masks capable of minimizing uneven streaks, shadow masks, and color picture tubes.The Fe-Ni alloy material is obtained by hot-rolling, pickling, cold-rolling and annealing, or by pickling, cold-rolling and annealing a plate produced by quick-solidifying molten Fe-Ni alloy so as to give an Ni segregation ratio of up to 6% after Fe-Ni alloy solidifying. |
