NdFeB permanent magnet material overview
1. NdFeB magnets introduction
NdFeB magnets, also known as NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron (Nd2Fe14B). NdFeB is the third-generation rare earth permanent magnet, which is called “Magnetic King” because of its excellent performance.
High-performance NdFeB refers to sintered NdFeB permanent magnet materials whose sum of intrinsic coercivity (HcikOe) and maximum magnetic energy product ((BH)maxMGOe) is greater than 60.
2. NdFeB permanent magnet material classification
NdFeB permanent magnet material is the representative of rare earth permanent magnet material. According to different production processes, it can be divided into three types: sintering, bonding and hot pressing.
Sintered NdFeB is currently the most widely used rare earth permanent magnet material.
3. NdFeB permanent magnet material application field
Compared with traditional permanent magnet materials, NdFeB has excellent permanent magnet properties and high cost performance.
At present, sintered NdFeB is widely used in automobiles (electric drives, electric power steering and sensors, etc.), wind power generation, information industry (hard disk drives, CD drives), consumer electronics (mobile phones, digital cameras), household appliances (inverter air conditioners, refrigerators and washing machines), elevator linear motors, nuclear magnetic resonance imagers and other fields.
