NdFeB Permanent Magnet
NdFeB Permanent Magnet Features:
NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal
elements,which has the high remanence,high coercive force,high
energy and high performance/cost ratio.The highest magnetic
properties is from 33MGOe to 52MGOe,and we are able to control the
magnetic properties within the range as you demanded,like SH,UH,EH
such high stable properties could be produced as per your
industrial application.
We focus on Sintered NdFeB magnet and develop it under experienced
engineer and passionate&studious sales team.

NdFeB Permanent Magnet production process:
Neodymium magnets are actually composed of neodymium, iron and
boron (they are also referred to as NIB or NdFeB magnets). The
powdered mixture is pressed under great pressure into molds. The
material is then sintered (heated under a vacuum), cooled, and then
ground or sliced into the desired shape. Coatings are then applied
if required. Finally, the blank magnets are magnetized by exposing
them to a very powerful magnetic field in excess of 30 KOe.
NdFeB application range:
Electroacoustic field: speakers, receivers, microphones, alarms,
stage sounds, car audio, etc.
Electronic appliances: permanent magnet mechanism vacuum circuit
breaker, magnetic holding relay, electric meter, water meter, sound
meter, reed switch, sensor, etc.
Motor field: VCM, CD/DVD-ROM, generator, motor, servo motor, micro
motor, motor, vibration motor, etc.
Mechanical equipment: magnetic separation, magnetic separator,
magnetic crane, magnetic machinery, etc.
Healthcare: Nuclear magnetic resonance instruments, medical
devices, magnetic health products, etc.
Other industries: magnetized wax protectors, pipe cleaners,
magnetic fixtures, automatic mahjong machines, magnetic locks, door
and window magnets, luggage magnets, leather bags, magnetized fuel
savers. Magnetic toys, magnetic tools, magnetic craft gift
packaging, etc.
