Magnet Applications has announced a major upgrade to its neodymium compression-bonded magnet product offerings. The new B12 magnet has a typical maximum energy product (BHmax) of approximately 12 MGOe, compared to the previous generation’s 10 MGOe.

The BHmax of a bonded magnet is determined by the density and the volume fraction of the magnetic material phase present in the magnet body. Magnet Applications engineers were able to improve performance by optimizing the particle size, particle distribution, chemistry, process and pressing conditions.

The new B12 magnet has a maximum operating temperature of 150° C, and is available in nearly any geometry and size.

“This significantly improved design has a 10% improvement in flux density [over] our previous generation of 10 MGOe,” said Applications Engineer Bob Fredette, who developed the new B12. “This higher performance will support the increasingly demanding designs for PM motors, encoders and magnetic sensors in several industrial applications.”
