Custom Neodymium Iron Boron Magnets
The Most Powerful Class of Permanent Magnet Materials Available Today
Neodymium Iron Boron (NdFeB) magnets
are part of the rare earth magnet family, and are extremely powerful and versatile. Components that were once large and heavy by necessity, can now be miniaturized by using these permanent magnet materials. This often results in a substantial cost savings for the completed magnet assembly. High in strength and less brittle, but more temperature sensitive than the SmCo types of rare earth magnets, neodymium magnets are often the more cost effective choice.

Sizes & Shapes: Neodymium iron boron rare earth magnets range in size from micro-dimensions (0.010") to assemblies weighing several tons. Standard shapes include discs, blocks, rings, and arc segments in different grades. Non-standard shapes can be custom fabricated to specifications from raw stock.
Manufacturing: Due to the relatively brittle nature and high magnetic strength of NdFeB magnets, cutting and grinding should be done prior to magnetization. Integrated Magnetics can custom manufacture neodymium custom magnets in virtually any shape and size to meet your requirements, using our in-house grinding and EDM facilities. Finishing to tolerances of +0.0001" can be achieved, as required.
:NdFeB magnets are susceptible to oxidation, so painting, epoxy coating, or plating is highly recommended to prevent corrosion. Integrated Magnetics can coat your custom magnets with a wide variety of materials, including nickel plating, IVD, or epoxy coatings.
Temperature Considerations: Neodymium magnets are temperature sensitive. For applications in which the magnet may be exposed to temperatures in excess of about 250°F (120°C), careful consideration must be given to the choice of magnet grade and the magnetic circuit.
Magnetizing & Handling
: Sintered neodymium rare earth magnets are anisotropic and have a strongly preferred magnetic orientation, while isotropic bonded NdFeB materials, though weaker, can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. Magnetizing fields in excess of 35 kilo Oersteds are required to magnetize these materials. NdFeB materials are mechanically weak, but are magnetically very strong. They must therefore be handled carefully to avoid injury to personnel and damage to the magnets.
: Neodymium rare earth magnets are frequently used in holding systems requiring very high holding forces, high field yoke magnets, magnetic bearings, magnetic couplings, loudspeakers, Halbach arrays, headphones, microphones, magnetic separation, instrumentation, switches, relays, magnetic resonance, sputtering, vacuum deposition, charged particle beam guidance, particle accelerators, undulators, wigglers, high performance stepper, DC, servo, linear, voice coil motors, and more.
