Sintering NdFeB		Bonded NdFeB

Brief introduction

NdFeB，the third generation of rare earth permanent magnet, has the high romance, high coercive force, high energy product and high performance/cost ratio. It is easily formed into various shapes and sizes and widely used in many fields such as aviation, electronics, instruments, meters, motors, medical instruments and the like.
