NdFeB permanent magnet material overview
1. NdFeB magnets introduction
NdFeB magnets, také známé jako NdFeB magnety, jsou tetragonální krystaly tvořené neodymem, žehlička, a bor (Nd2Fe14B). NdFeB je třetí generace permanentních magnetů vzácných zemin, který se nazývá “Magnetický král” kvůli jeho skvělému výkonu.
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 klasifikace
NdFeB permanent magnet material is the representative of rare earth permanent magnet material. Podle různých výrobních procesů, it can be divided into three types: slinování, 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.
V současnosti, sintered NdFeB is widely used in automobiles (electric drives, electric power steering and sensors, atd.), wind power generation, information industry (hard disk drives, CD drives), consumer electronics (mobilní telefony, digitální fotoaparáty), household appliances (inverter air conditioners, refrigerators and washing machines), elevator linear motors, nuclear magnetic resonance imagers and other fields.
