Product Description

Sintered NdFeB Magnet Industrial Magnets Super Powerful Magnet Neo Magnetic Attraction
 
NdFeB magnet
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.

More details:
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
Moderately priced
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.
 
Advantage
1) Excellent temperature stability
2) Small size and light weight
3)Strong magnetism
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.

 
The process
1.Preparation of raw materials: IQC
2.Melting & strip casting: Analysis of element content, strip casing structure and crystallization
3.Pulverizing and jet milling: Inspection of particle size distribution
4.Pressing immagnetic field: Inspection of size and appearanceof green body
5. Sintering and aging:Inspection of size, appearance, density and oxygen content magnets
6.Machining: Inspection of size and appearance of magnets
7.Coating: Inspecion of size, appearance of magnet, thickness, adhesion and anti-corrosion
8.Magnetizing: Inspection of magnetic propertes of magnet
9.Packing
