(Bonded) Neodymium Iron Boron (NdFeB) Magnets

BREMAG (molded neodymium iIron boron, or NdFeB) rare earth magnets open up a new realm of design possibilities to engineers. Their high magnetic values and reduced size make them ideal for miniaturization where weight and space are at a premium.

Our unique abilities in the production of compression molded Bremag increase the scope of its application. No other magnetic material combines these performance and fabrication capabilities. Plus, Bremag simplifies production engineering because of its resistance to chipping and cracking, its complex magnetization (click here for magnetization patterns) possibilities and its machinability.

Additionally, we have had success with hybrids of neodymium iron boron and ferrite, offering our customers an even broader range of choices.

We offer complete engineering assistance, prototyping services, fabrication and inventory management. Call our sales staff today to discuss your application.

Coatings

The epoxy binder in Bremag does offer limited protection against corrosion which is suitable for many applications. In more demanding operating conditions, e.g. in high temperature and/or humid conditions, a coating may be necessary; we supply in volume series, a number of different coatings which have different merits and we invite you to discuss with us the correct solution for your application.

Compression bonded neodymium iron boron (NdFeB) offers:

  • Excellent mechanical strength and surface finish
  • Compression molded magnets can be manufactured to very tight tolerances
  • Greater cracking and chipping resistance than other rare earth magnets
  • Superior energy to weight ratio
  • May be molded into a variety of shapes and sizes
  • Magnetic values up to 10 MGOe
  • Simple to complex multipole magnetization patterns possible
  • Low tooling cost
  • Co-injected assemblies
