Abstract

A Fe—Ni—Co based alloy being improved in proof stress and Young's modulus as indexes for the resistance to fall impact deformation while maintaining low thermal expansion properties for use in a completely flat mask of a press-formed type, which comprises, in mass %, 30 to 35% of Ni, 2 to 8% of Co and 0.01 to 0.5% of Mn, and further comprises one or more selected from among 0.01 to 0.8% of Nb, 0.01 to 0.8% of Ta and 0.01 to 0.8% of Hf in an total amount of 0.01 to 0.8%, the balance of the alloy being Fe and inevitable impurities; and a completely flat mask and a color cathode-ray tube using the Fe—Ni—Co based alloy. It is preferred that the contents of C, Si, P, S and N as impurities in the ally are controlled to 0.01% or less, 0.04% or less, 0.01% or less, 0.01% or less and 0.005% or less, respectively.
