NdFeB Magnetic Powder can be divided into Bonded NdFeB Magnetic Powder and Sintering NdFeB Magnetic Powder. Bonded magnetic powder produced by Melt Spining. Bonded NdFeB Magnetic Powder can be divided into Isotropic ones and MQA ones. Isotropic Magnetic Powder is stable anti-oxidation and demagnetization performance. We mainly offer Bonded NdFeB Isotropic Magnetic Powder.
Characteristic of Bonded Magnetic Powder:
1. Easily produce complicated magnet shapes.
2. One time forming and multipolar orientation .
3. High precision of magnet dimension.
4. Good consistency of final products.
5.Good tenacity performance,not easy to broken or crack.
6. Better processing performance suitable for mass production.
7.High utilization ratio of raw material and lower producing cost.
