Neodymium-Iron-Boron Magnets / Countersink Neodymium Magnet
Neodymium-iron-boron (NdFeB), or “neo”, magnets offer the highest energy product of any material today and are available in a range of shapes, sizes and grades. Neo magnets can be found in a wide variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
Magnetic properties will differ depending upon alignment direction during compaction and upon size and shape. Download individual spec sheets from the table below, or get the full neo catalog here for specific grades and their magnetic properties, including the trade-off in Br (and energy product) for HcJ (intrinsic coercivity, resistance to demagnetization).
Maximum Use Temperature and Corrosion
Determining whether or not to use neo magnets instead of our SmCo magnets, for example, is a function of the maximum temperature of the application, required magnetic output at typical use temperature and total cost of the system.
Although the Curie temperature for neo materials is 310 degrees for 0% cobalt-containing material to greater than 370 degrees for 5% cobalt-containing, some irreversible loss of output may be expected at even moderate temperatures. Neo magnets have a moderately high Reversible Temperature Coefficient of Induction which reduces total magnetic output as temperature rises.
Neo magnets also have some limitations due to their corrosion behavior. In humid applications, a protective coating is highly recommended. Coatings which have been used successfully include, E-coat (a liquid dip epoxy coating), dry electrostatic spray epoxy, nickel plating and combinations of these coatings. Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance.
