Key AdvantagesNeodymium magnets are the most powerful commercially produced magnets.NdFeB magnets have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.NdFeB magnets can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.Very high strength.Relatively low cost.Compared to Alnico and SmCo magnets, relatively easy to machine.Quick LeadsManufacturing process - sintering (most common), injection molding, and compression bonding.Shapes available - blocks, bars, discs, rings, cylinders, arc segments, or irregular shapes, etc.Wide range of Grades available- from about 3330 to 5311. (First 2 digits represent BH.max, and second two digits represent Intrinsic Coercivity, Hci.)Density: 7.4 -7.6 g/ cm3; Hardness: 600 {Hv}Some particular grades of Stanford Magnets can achieve 200°c the max working temperature.Saturation magnetizing field required - about 35kOeMachining - Neodymium magnets should be machined by grinding using diamond wheels, however, of the hard magnet materials, Neo magnets are the least difficult to machine. We can successfully machine very small magnets.Common Applications

Sensors   Linear actuators   Microphone assemblies    Magnetic separators   DC and servo motors   Speakers   Printers   Magnetic hooksComputer rigid disc drives   Beam controls   Intelligent toys   MRI/NMR
