Neodymium iron boron magnets, also known as Nd2Fe14B magnets, neodymium magnets, neo magnets, Nd-Fe-B magnets, RE2TM14B magnets, or simply 2:14:1 magnets, were developed in the 1980s. Nd2Fe14B has a tetragonal crystal structure. The heavy rare earth element, dysprosium, is often added to increase intrinsic coercivity and maximum operating temperature. Small amounts of other transition metals, such as Al, Co, Cu, Nb andor Ga, can be added to modify the microstructure to improve performance.KEY FEATURES OF SINTERED NdFeB MAGNETS INCLUDE: Highest room temperature maximum energy product, (BH)max, up to 52 MGOe Relatively less expensive Wide range of choices for a variety of applications
