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.

001 to 2.0 wt% is O,001wt%
Below 2.0w, corrosion resistance against slit corrosion does not appear.
This is because if the amount exceeds t%, the improvement effect due to addition will not be recognized.
