Abstract
In an Fe-base alloy, Ni is contained by 28 to 34% by weight and Co by 2 to 7% by weight with an average grain size of 30 .mu.m or less. 60 to 95% of crystal grains are oriented in a range of .+-.5 to 45 degrees deviated from the ideal orientation of {100} [001]. Resultant low thermal expansion of the alloy assures high doming characteristics of a shadow mask made thereof.
