1.NdFeb owns higher sensitivity than AlNiCo and SmCo magnets;
2. more fitting for loudspeaker with smaller size;
3. easy to cut , drilled and even more complex shaped;
4. BHmax can be 5-12 times stronger than Ferrite and 3-10 times than AlNiCo;
5. coercivity force can be 5-10 times stronger than Ferrite and 5-15 times stronger than AlNiCo;
6. high potential magnetic property, can pull something of 640 times heavy of its own weight ;
7. Max working temperature is 80℃ which can be extended to 200℃ after special treatment;
8. rich in Neodymium and ferrum, easy got rusted.
