Ring magnets
Sintered NdFeB
neodymium-iron-boron(NdFeB) magnets, rare earth magnets, permanent magnets,most powerful and commercialized, customized
1. Material: Sintered Neodymium-Iron-Boron.
2.The strongest power magnets in all of the permanent magnets.
3. Grade: N35 to N52; N35M to N50M; N35H to N48H, N35SH to N45SH; N30UH to N40UH, N30EH to N38EH.
4. Excellent strength value: the highest (BH)max reaches up to 51MGOe.
5. Extremely Resistance to demagnetization with Hci,the intrinsic coercive force is over 30000Oe.
6. Moderate temperature stablity: under 80℃ for low Hci NdFeB magnet and above 200 ℃ for high Hci NdFeB magnet.
7. Coating: Effective Surface treatment to prevent corrosion, such as Nickel, Ni-Cu-Ni co, Zinc, gold, siliver, tin(Sn), epoxy, chemical, parylene, etc.
8.Shapes and sizes: various according to clients' request
9. Advanced techniques: new techniques and equipment such as strip casting, HDDR technology
