    Bonded NdFeB Bonding Neodymium Iron Boron 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.

    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. Ring Compression Molded NdFeB Magnet

    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. Ring Compression Molded NdFeB Magnet

    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. ring bonded ndfeb magnet

    Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
    ► Head actuators for computer hard disks
    ► Magnetic resonance imaging (MRI)
    ► Magnetic guitar pickups
    ► Mechanical e-cigarette firing switches
    ► Locks for doors
    ► Loudspeakers and headphones
    ► Magnetic bearings and couplings
    ► Benchtop NMR spectrometers
    ► Electric motors:
    ● Cordless tools
    ● Servomotors
    ● Lifting and compressor motors
    ● Synchronous motors
    ● Spindle and stepper motors
    ● Electrical power steering
    ● Drive motors for hybrid and electric vehicles.
    (Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.)
    ● Actuators

    ► Electric generators for wind turbines(only those with permanent magnet excitation)
    ● direct-drive wind turbines require c. 600 kg of PM material per megawatt
    ● turbines using gears require less PM material per megawatt
