Sintering NdFeB	Bonded NdFeB
	Ferrite Magnets
	Casting AlNiCo
	FeCrCo Magnets
	SmCo Magnets

....NdFeB magnets that appeared at the early of 1980 are recognized as the third generation rare earth permanent magnets and the magnetic force is the most powerful. It can be divided into Sintering NdFeB magnets and Bonded NdFeB magnets.

....Comparing to sintering NdFeB magnets, Bonded NdFeB magnets have the features of being shaped for one time, magnetization in various orientations. They are mainly used in micro-motor.
