What is a sintered neodymium magnet?
Sintered Nd-Fe-B magnet is one of the most powerful permanent magnetic materials in the world. Compared with traditional permanent magnet materials, sintered NdFeB has excellent permanent magnetic properties and high cost performance. Sintered NdFeB has greatly expanded the application potential of permanent magnet materials. It has been widely used in transportation, energy, communication, household appliances, machinery and medical treatment, and is playing an important role in green energy and artificial intelligence. It has become an indispensable functional material in production and life.
Sintered NdFeB magnets are mainly used in automobile (electric drive, electric power steering and sensor, etc.), wind power generation, information industry (hard disk drive, optical disk drive), consumer electronics (mobile phone, digital camera), household appliances (frequency conversion air conditioner, refrigerator and washing machine), elevator linear motor, nuclear magnetic resonance imaging instrument, etc The applications of manufacturing, intelligent driving and intelligent service are in the ascendant.
