Bonded NdFeB is easily machined. Coolants must be used while machining this material in order to avoid spontaneous combustion of powder. Machining this material removes a layer of protective coating, and re-coating for corrosion resistance may be necessary.
MAGNETIZING AND HANDLING
All Rare Earth magnets require extremely high magnetizing fields and special consideration must be given to this when designing complex assemblies, if it is intended to magnetize after assembly. Consult us if you foresee any problems.
Rare Earth materials are mechanically weak, and magnetically very strong. They must therefore be handled very carefully to avoid damage and injury to personnel handling the magnets. Receiving and assembly personnel should be warned about the dangers of handling magnetized Rare Earth magnets.
Isotropic bonded NdFeB materials can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization. Such multiple pole fixtures may cost several thousand dollars depending on complexity of design and production rate requirements.
Magnetic properties of NdFeB deteriorate rapidly above about 130C, depending on the grade of material, and the permeance coefficient of the magnet in operation. The higher the permeance coefficient the magnet operates at, the higher the temperature it will withstand. High H ci NdFeB materials operating at a high permeance coefficient can operate to about 210C.
Common Applications for Neodymium Iron Boron Magnets
Holding systems requiring very high holding forces, high field yoke magnets, high performance stepper, DC, servo, linear, and voice coil motors, 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, and others.
A company wanted a magnet on a joystick to activate Hall Effect sensors to give relative position information. A ferrite magnet would be too weak; a sintered NdFeB neodymium magnet would be too powerful. A compression bonded NdFeB magnet was supplied that had a performance between NdFeB and Ferrite but which had an epoxy finish, good final tolerances and would be low cost in high production quantities.
