NdFeB Magnet Grades: Full N30-N54 Property Table

The table below lists every standard sintered NdFeB grade we supply, from N30 to N54 and the M, H, SH, UH, EH, AH, and TH temperature classes. Remanence (Br), intrinsic coercivity (Hcj), coercivity (Hcb), maximum energy product (BH)max, temperature coefficients, and maximum working temperature are shown per grade.

The letter suffix indicates temperature class: no suffix (N) is rated to 80°C, M to 100°C, H to 120°C, SH to 150°C, UH to 180°C, EH to 200°C, and AH/TH to 220–260°C. Higher-coercivity grades use heavy rare earth additions and cost more; most applications are served by N35–N52. If you are unsure which grade fits your operating temperature and demagnetizing field, send us your drawings and our engineers will recommend one.
