Title:
磁石粒子およびそれを用いた磁石成形体
Document Type and Number:
Japanese Patent JP6439876
Kind Code:
B2
Abstract:
[PROBLEM] To provide a bond magnet molding which has such a large electrical resistance that an induced current can be reduced even when used in a usage environment subject to magnetic field variation. [SOLUTION] The problem is solved by means of a bond magnet molding characterized by containing, as a binder, a Zn alloy having a strain rate sensitivity exponent (m value) of not less than 0.3 and an elongation at break of not less than 50%, wherein magnet particles of a nitrogen compound containing Sm and Fe are solidified using the binder at a temperature not higher than a molding temperature.
