Residual Magnetic Flux Density (Br): 1250-1280 mT (12.5-12.8 kGs)
Energy Density (BH)max: 302-326 KJ/m³ (38-41 MGOe)
Coercivity Force (Hcb): ≥ 907 kA/m ( ≥ 11.4 kOe)
Intrinsic Coercivity Force (Hcj): ≥ 955 kA/m ( ≥ 12 kOe)
Maximum Operation Temperature: 80 °C

Advantages:
• Highest magnet strength available
• High resistance to demagnetization
• Operating temperature up to 240ºC
• Good at withstanding low temperatures (down to – 100ºC)
Corrosion protection is however always recommended for sintered neodymium magnets, because of the materials low corrosion resistance. The corrosion resistance of sintered NdFeB magnets can be compared to pure untreated iron.
A range of different coatings are available but sometimes complete encapsulation in i.e. stainless steel is preferable.
