DUBOIS, PA – Magnet Applications®, Inc., a leading provider of compression bonded magnets, injection molded magnets and magnetic assemblies to the automotive, medical, defense and aerospace industries, today announced the release of a major upgrade to its industry-leading neodymium compression bonded magnet product offeringsthe all-new high energy B12. The new B12 has a typical maximum energy product, (BH)max, of approximately 12 MGOe compared to the previous generation of 10 MGOe.

The (BH)max of a bonded magnet is determined by the density and the volume fraction of the magnetic material phase present in the magnet body. By optimizing the particle size, particle distribution, chemistry, process and pressing conditions, Magnet Applications engineers have achieved a breakthrough in performance.

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

Magnet Applications, Inc. expects to see the new magnet in motors for automobiles, transportation, aerospace, defense and other high-heat environments due to its strength and operating temperature. B12 has a maximum operating temperature of 150°C is available in nearly any geometry and size.
