である等の理由によってこれらの欠点を補う磁性材料と
してＭ−８ｉ−Ｆｅ系のセンダスト系合金が注目されて
いる。Conventionally, permalloy, ferrite, etc. have been used as magnetic materials for magnetic helad cores, but as a result of the advent of chromium oxide tape, which easily wears the mating material, and the spread of magnetic cards, permalloy has problems in terms of wear, and ferrite The M-8i-Fe based sendust alloy is attracting attention as a magnetic material to compensate for these drawbacks, especially when the card is a magnetic card.

点があり、その改善が強く要望されていた。However, when conventional Sendust alloys are used as magnetic materials for magnetic helad cores, they may discolor if exposed to salty humidity, especially in coastal areas, or the core gap may deteriorate during use. There are problems such as slit corrosion occurring when moisture penetrates into the parts, and there has been a strong desire to improve this problem.
