To provide an Fe-Ni sheet which is suitable for micro-machining and reduced in the occurrence of punched burrs, and to provide an Fe-Ni punched parts.
This Fe-Ni sheet reduced in the occurrence of punched burrs has a face-centered cubic structure, and its degree of texture of the {200} crystalline plane of a punched surface is ≥70%. This novel Fe-Ni punched parts which has the face-centered cubic structure, whose degree of texture of the {200}, crystalline plane of the punched surface, is ≥70%, and whose punched burr length is ≤2%, preferably ≤1%, and more preferably ≤0.5% of the sheet thickness can be obtained by punching the Fe-Ni sheet. The Fe-Ni sheet is applicable to a known Fe-Ni alloy which has a composition consisting of 40-90 wt.% Ni and the balance Fe, or in which a third element such as Mo, Cr or Cu is substituted for a part of Fe.
