Neodymium-Iron-Boron Magnet Catalogs

 Neodymium-Iron-Boron magnets are available in a very wide range of grades, shapes and sizes. Magnetic properties will differ depending upon alignment direction during compaction and upon size and shape. 

 Arnold Neo Magnets (Neodymium-Iron-Boron) are  RoHS compliant .

 Arnold Magnetic Technologies is also a supplier of the austriamicrosystems magnet.  Arnold part number 81X0564-2 is made for use with the AS50xx encoder.  Buy now from our ecommerce site.

 The graph below represents generally available magnet properties, demonstating the trade-off in Br (and energy product) for HcJ (intrinsic coercivity, resistance to demagnetization).
