| 简介 |
To provide a rare earth bonded magnet high in intensity at a high temperature and small in changes over time of thermal demagnetization.SOLUTION : A rare earth bonded magnet includes a rare earth magnet particle, a first binder resin cured product, and a second binder resin cured product. The first binder resin cured product has a glass transition point (Tg) of 150°C or above, and the second binder resin cured product has a glass transition point (Tg) of less than 150°C. The glass transition point (Tg) of the second binder resin cured product is preferably 130°C or below.SELECTED DRAWING : Figure 1 |
