All-new high energy B12 magnets from Bunting Magnetics Co.'s Magnet Applications, Inc. (DuBois, PA) are a major upgrade to its neodymium compression bonded magnet product offerings, according to the company. 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 says its engineers have achieved a breakthrough in performance. The company 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.
