Abstract

There is provided an Fe-Ni alloy containing, all by weight, 30 to 55% Ni, 0.5% or less Si, 1.5% or less Mn, 0.2% or less Al, 0.005 to 0.020% O, and 0.020% or less S. There is also provided a punched electron gun part made of the above Fe-Ni alloy. Typeical of the punched parts for electron guns is an electron gun electrode. By controlling the oxygen content within specified range and, if necessary, by controlling both oxygen and sulfur contents within specific ranges, the punching properties of the Fe-Ni alloy is improved. In the case where the improvement of the punching properties is solely or strongly sought, S content should be in the range of 0.002 to 0.20%, whereas when the deterioration of corrosion resistance must be considered, S content should be less than 0.002%. The oxygen is mostly present as inclusions in the alloy and enhances its punching properties.
