ABOUT BONDED NEODYMIUM

For a more flexible alternative to sintered neodymium, consider using bonded neodymium magnets for your application. Bonded neodymium powder is used to create these magnets. Powder is melted and mixed with a polymer. Components are then cast or extruded to create the product. Bonded Neodymium magnets can be magnetized into complex patterns with many poles. Bonded neodymium magnets are much weaker than Sintered Neodymium magnets but gives greater flexibility in terms of shapes that are able to be made. Neodymium magnets are lighter than Samarium Cobalt, however, they have a lower acceptable temperature. Neodymium offers excellent value for applications that require a smaller-sized magnet.
