Description:

Among the existing soft magnetic materials, the alloy has the highest saturation magnetic induction (2.4T), the Curie point is also high (980°C), and the saturation magnetostriction coefficient is the largest (60-100×10-6). Due to the high saturation magnetic induction, the volume can be greatly reduced when the motor of the same power is made, and when it is used as an electromagnet, it can produce a large attracting force under the same cross-sectional area. Due to the high Curie point, the alloy can work at a higher temperature where other soft magnetic materials have been completely demagnetized, and maintain good magnetic stability.
