Sintered NdFeB Magnet Industrial Magnets Super Powerful Magnet Neo Magnetic Attraction
Ndfeb magnet,the third generation of rare-earth permanent magnet,is the most powerful and advanced permanent magnet today.Ndfeb is named as “Magnet King”for its high remanence,high energy.Moreover,it has the high performance and high cost ration, because of the rich rare earth resources in China and the ever-changing production process and technological progress.It can be easily formed into various sizes and different shapes ,such as segment.ring,block and etc.
Sintered Rare Earth NdFeB Magnet: is one of the high performance rare earth permanent magnets, which use neodymium (Nd), iron (Fe), and boron (B) as their main ingredients.
Direction of magnetisation:
Special requirements for custom magnetization
Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron and a few transition metals
Like SmCo magnets, NdFeB magnets are produced by the process of powder metallurgical sintering. Sintered NdFeB magnets have the character of brittleness and hard, thus need to be handled carefully
This material is easy corrosive, so its surface is usually treated with some special methods. The surface treatment method include zinc, nickel.
Because of its very high resistance to demagnetization, reasonable temperature stability, high energy for size and good cost to performance ratio
Applications: magnetic separators, linear actuators, microphone assemblies, servo motors, DC motors (automotive starters), computer rigid disc drives, alternators, printers and speakers
Attributes of NdFeB materials:
Very high resistance to demagnetization
High energy for size
Good in ambient temperature
Material is corrosive and should be coated for long term maximum energy output
Size and Shape:D3--D280mm(round)Cylindrical, Ring, Square, Holed Square, Watt, Arch, or Customized.
1) Excellent temperature stability
2) Small size and light weight
4)Relatively high energies characterize
5) High performance-to-price ratio,widely used
Usage of magnet
1). Electronics – Sensors, hard disk drives, sophisticated switches, electro-mechanical devices etc.;
2). Auto Industry – DC motors (hybrid and electric), small high-performance motors, power steering;
3). Medical – MRI equipment and scanners;
4). Clean Tech Energy – Water flow enhancement, wind turbines;
5). Magnetic Separators – Used for recycling, food and liquids QC, waste removal;
6). Magnetic Bearing – Used for highly sensitive and delicate procedures in various heavy industries.
