As a result of taking into account in detail the effect of each of the Co content and the trace element range on the properties of the Invar alloy as well as the phenomenon occurring in the inner shape of the etching hole formed by etching, the alloy of the present invention It has been found. Hereinafter, the alloy components constituting the present invention and the reasons for the limitation will be described.

In the case of the present invention, in addition to the adjustment of the amount of Mn to be described later, by solving the problem of the etching property due to the low Mn, the excellent low thermal expansion characteristic based on the effect of the Co content of the present invention is achieved. We have found a means that can achieve this and also achieve excellent etching properties.

%, The significant difference can be obtained. Specifically, excellent low thermal expansion characteristics are achieved with a Co content exceeding 2.5%. In addition, Co has a very high raw material cost and a content exceeding 7% saturates the effect of improving the low thermal expansion characteristic. Therefore, in the present invention, the content of Co exceeds 2.5% to 7%. It was as follows.

In the Fe—Ni—Co-based alloy of the present invention in which an appropriate amount of o is added, the adjustment of the C content is effective in compensating for an obstacle to the etching property due to the Co addition. That is, the addition of Co lowers the etching rate, and there is a fear that distortion of the etching hole may occur. Then, when it examined in order to improve this subject, Fe-Ni-C which has Co content of this invention

が解消でき、正常なエッチング孔を形成でき得ることを
突きとめた。By limiting the S: Mn content from the conventional 0.25% level to less than 0.1%, a new problem (FIG. 2) arises that the contour of the inner hole of the etching hole is deformed jaggedly. In this case, there is a possibility that a problem may occur in application to a shadow mask requiring high definition (particularly, a shadow mask for a personal computer). When this problem was investigated, it was found that the process differs from the distortion of the etching hole due to the decrease in the etching rate in view of the site where the problem occurred. Then, when various trace elements were investigated, it was found that this problem could be solved by suppressing the amount of S to be low, and a normal etching hole could be formed.

しい。That is, the phenomenon that the inner contour of the etching hole is jagged is caused by the fact that S in the matrix is not fixed by reducing the amount of Mn, and the amount of S existing in the grain boundary increases. It is thought to be the result of increased susceptibility. In order to solve this problem, it is effective to suppress the amount of S. In the case of the present invention, suppressing S to 0.0015% or less is necessary for obtaining a shadow mask having excellent smoothness of the inner shape of the etching hole. preferable.

The effect of increasing the coefficient of thermal expansion can be sufficiently eliminated.
