  2.NdFeB Magnet Basic Information:

Made of Neodymium, Iron, Boron and sometimes Dysprosium.

Sintered (pressed and baked). They are often used in sensor applications because of their long feild depth.

They most commonly appear slightly rough with shiny nickel plating. Without the plating they are light grey.

They are strong enough to magnetize and demagnetize some sizes of Alnico and flexible material.

The most common grades of NdFeB are 30 and 35.

The optimum geometry for NdFeB is flat pancake shaped. The thickness is best to be about 1/8 of the diameter. Magnetized through the thickness.

Custom sizes available in 3-4 weeks. Stock sizes and price list available upon request by E-mail.

  3. Engineering Information :     

MANUFACTURING RARE EARTH  MAGNETS

   In general, the elements are melted together and then milled into a powder that is dry pressed to shape in the presence of a magnetic field. Then the material is sintered, aged, ground to dimension, magnetized and tested.

     They are called “rare earth” magnets because the elements of neodymium and samarium are classified as such in the lanthanides section of the periodic Table of the Elements.

NEODYMIUM

ATTRIBUTES OF CERAMIC MAGNETS

  • Very high resistance to demagnetization
  • High energy for size
  • Good in ambient temperature
  • High priced
  • Material is corrosive and should be coated for long term maximum energy output
  • Low working temperature for heat applications

APPLICATIONS OF SAMARIUM

         Magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors( automotive starters), computer rigid disc derives, hammerbank printers, and speakers .

SAMARIUM

ATTRIBUTES OF SAMARIUM

  • High resistance to demagnetization
  • High energy (magnetic strength is strong for its size )
  • Good temperature stability
  • Expensive material (cobalt is mark price sensitive )

APPLICATIONS OF SAMARIUM

  • Computer disc drives
  • Sensors
  • Traveling wave tubes
  • Linear actuators
  • Satellite systems
  • Motors where temporary stability is vital

RARE EARTH TOLERANCES

    For as pressed material, tolerances on the thickness (direction of magnetization ) are ±.005. Other dimensions are ±2.5% or ±.010 whichever is greater.

    According to Magnet Materials Producers (MMPA) standards, visual imperfections such as hairline cracks, Porosity & minor chips are commonly found in sintered metallic magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of a pole surface .

RARE EARTH MAGNETIZING & HANDLING

         Rare earth magnets are very brittle and very strong magnetically. therefore, it is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets. Fingers can be severely pinched between attracting magnets. Magnets can Chip if allowed to jump at an attracting object. It is highly recommended that when constructing rare earth magnetic assemblies, they be magnetized after assembly.

RARE EARTH MACHINING

        Since rare earth magnet material is prone to chipping and cracking , it does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust .
