Compression bonded magnets
Dubois, Pennsylvania – Magnet Applications Inc., part of Bunting Magnetics Co. and a provider of compression bonded magnets, injection molded magnets, and magnetic assemblies to the automotive, medical, defense, and aerospace industries, has released a major upgrade to its neodymium compression bonded magnet product offerings. 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.
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.
Magnet Applications Inc. is ITAR/DFARS and ISO 9001:2008 registered.
