NdFeB magnet
Neodymium iron boron ( NdFeB) is a type of rare earth magnetic material.
NdFeB is the most advanced commercialized permanent magnet material available today.This material has similar properties as the samarium cobalt except that it is more easily oxidized and generally doesn't have the same temperature resistance.
However, NdFeB magnets have the highest energy products approaching 52MGOe and are mechanically stronger than samarium cobalt magents. NdFeB material is more costly by weight than ceramic or alnico but produces the highest amount of flux per.
A unit of volume or mass it very economical for many applications. Their high energy products I end themselves to designs that result in innovative and lower manufacturing costs.
Common Usage of neodymium magnets
1.Servomotor, step motor, DC motor and linear motor
2.Loudspeaker, headphone, earphone and microphones
3.Clothes accessory, clothes and bags’ button
4.Medical Industry: Medical equipment, Magnetic therapy products
5.Holding system equipment
6.Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices
7.Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;
8.Medical – MRI equipment and scanners;
9.Clean Tech Energy – Water flow enhancement, wind turbines;
10.Magnetic Separators – Used for recycling, food and liquids QC, waste removal;
11.Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.
Advantages of Sintered Magnet
1.The NdFeB magnet has high remanence, high coercive force, high energy product and high ratio between performance value and product cost.
2.It can be easily formed into various sizes.Various shapes on offer: block, round, ring, arc-even highly complex forms. Virtually any shape of neodymium
3.Smaller size and lighter weight in designing devices
4.High energy range from 30MGOe to 53MGOe with wonderful coercive force
