Neodymium-Iron-Boron (NdFeB) Magnets for Servo Motor

As the strongest permanent magnet in the world, sintered NdFeB has excellent permanent magnetic properties and high cost performance compared with traditional permanent magnet materials. Sintered NdFeB magnets greatly expand the applications of permanent magnets. They are widely used in the fields of transportation, energy, communications, home appliances, machinery and medical equipment.


ZHAOBAO has many years of design and research & development experience, we have been committing ourselves to the development and production of high coercive force, low reversible temperature coefficient and low weight loss characteristics of NdFeB with high performance consistency and high quality. We can provide customers with customized sintered NdFeB and solutions.
