Neodymium Iron Boron


Neodymium Iron Boron Magnets

Known as rare earth magnets, Neodymium Iron Boron magnets are alloys of the Lanthanide group of elements. NdFeB magnets offer the highest energy product per unit mass, and highest energy product per unit cost of any current permanent magnet material.

Energy Products range from 30 to 55 MGOe, with recommended operating temperatures from 60º – 220ºC, and the temperature coefficient of residual induction ranges from -0.09 to -0.13%/°C.

Common Applications for Neodymium Iron Boron Magnets

Neodymium Iron Boron magnets are widely utilized in various applications


NdFeB Preparation

BJA Magnetics prepares its anisotropic powders by either casting an alloy with a mold, or strip casting. Strip casting offers the advantage of better chemical stability. Subsequently, the ingot from the mold or the flakes from strip casting are pulverized to a uniform grain/particle size. The best method for obtaining the desired grain size is by HDDR.

The HDDR [hydrogenation-decomposition-desorption-recombination] process yields a more homogenous particle size with a minimum of α-Fe, and Nd-rich phases. Anisotropic Nd-Fe-B, HDDR powders prepared from strip cast alloys are used for the HAST [Highly Accelerated Stress Test] grades of NdFeB Magnets, including N, H, SH, UH, EH, and BJA Magnetics exclusive “W” grades for Wind Power applications.
