1. Physical Properties of Permanent Neodymium Magnet:

a) NdFeB magnets offer the highest energy product of any material today and are available in a very wide range of shapes, sizes and grades.

b) NdFeB magnets have some limitations due to their corrosion behavior. In humid applications, a protective plating is highly recommended.  Platings which have been used successfully include, parylene,epoxy resin,zinc plating, gold plating, Ag plating,nickel plating and combinations of these platings.  Changes in composition and processing over the past several years have resulted in significant improvements in corrosion resistance and high temperature performance. 

2.Magnetic characteristics of Permanent Neodymium Magnet:   customized

3.Shape of Neodymium Magnet: Disc, Ring, Block, Segment, Cylinder, Trapezoid, Customized Design(Design proper magnets for clients specific requirements)

4.Tolerance: +/-0.05mm for small dimensions, +/-0.1mm for common specifications, +/-0.15mm for big blocks

5.Coating: Ni, Ni-Cu-Ni, Zn, Epoxy, Parylene, etc.

6.Applications: 

• Head actuators for computer hard disks
• Magnetic resonance imaging(MRI)
• Magnetic guitar pickups
• Mechanical e-cigarette firing switches
• 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. The electric motors of each 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
