Bonded NdFeB: Bonded Neodymium-Ferrite-Boron(NdFeB) is made from mixture of NdFeB powder and organic bonded chemical like epoxy resin, nylon, etc. It is shaped through moulds pressing, injection, extrusion, etc.
Characteristic:
1.the most powerful magnetic property in all the isotropic magnets.
2.can be shaped into high accurate and diversified components for one time without processing again.
3.good tenacity
4.good ability of anti-erosion
5.steady performance in temperature.
Application: Comparing to sintering NdFeB magnete, Bonded NdFeB magnete have the features of being shaped for one time, magnetization in various orientations. They are mainly used in micro-motor.
