Neodymium iron boron (NdFeB), or “neo” magnets offer the highest energy product of any material today and are available in a wide range of shapes, sizes and grades. Neo magnets can be found in a variety of applications including high performance motors, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors and loudspeakers.
Sintered Neodymium (NdFeB),the lanthanide series of elements in the periodic table, also known as a second generation rare earth magnet, are the most powerful magnets available today with outstanding magnetic properties. By some, they are considered exotic materials, even though significant amounts of ore deposits are found around the world. The two most commonly known rare earth magnets are: Sintered Neodymium Iron Boron (NdFeB) simply known as Neo’s and Samarium Cobalt (SmCo) magnets known as Cobalt magnets. Due to their high magnetic strength extreme caution should be taken during handling and assembly.
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 pressed or extruded to create the product. Bonded Neodymium magnets can be magnetized into complex patterns with multiple poles. Though much weaker than Sintered Neodymium magnets, Bonded neodymium magnets give greater flexibility in terms of shapes that can be made. They are also lighter than Samarium Cobalt, and have a lower acceptable temperature (coercivity). Nevertheless, they offer excellent value for applications that require a smaller magnet or utilize radial rings.Applications include automotive, home, power tools, as well as electronic industries.
