Key Advantages
  • Neodymium magnets are the most powerful commercially produced magnets.
  • NdFeB magnets have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
  • NdFeB magnets can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
  • Very high strength.
  • Relatively low cost.
  • Compared to Alnico and SmCo magnets, relatively easy to machine.
  • GradeMax. Energy ProductRemanenceCoercive ForceRev. Temp. Coeff.Curie Temp.Working Temp.
