Neodymium Magnets (Neodymium Iron Boron Magnets)

also known as NdFeB or Neo magnets, are the most widely-used type of rare earth magnet. It is the strongest type of permanent magnet made from an alloy of Neodymium, Iron, and Boron with the Nd2Fe14B tetragonal crystalline structure. It has replaced other types of magnets in many applications in modern products that require strong permanent magnets, such as motors in cordless tools, hard disk drives, and magnetic fasteners.

Density(g/cm3)	7.3-7.5
Curie Temperature (ºC)	320
Max. Operating Temperature (ºC)	220
Relative Permeability	1.05
Flexural Strength (N/nm2)	250
Compressive Strength (N/nm2)	1100
Tensile Strength (N/nm2)	75
Hardness (Hv)	550-650
Temperature Coefficient of Br (%/ºC)	-0.09~-0.12
Temperature Coefficient of Hcj (%/ºC)	-0.50~-0.65

Applications

Magnetic separators
DC and servo motors
Speaker Parts
Printers
Magnetic hooks
MRI/NMR
