Sintered NdFeB magnet is the strongest magnetic permanent magnet material in the world today. Compared with traditional permanent magnet materials, it has excellent permanent magnet characteristics and high cost performance. Sintered NdFeB magnet greatly expands the application potential of permanent magnet materials, widely used in transportation, energy, communication, home appliances, machinery and medical and other fields, and is playing an important role in green energy and artificial intelligence, has become an indispensable important functional material in production and life.Sintered NdFeB magnets are mainly used in automobiles (electric drive, electric power steering and sensors, etc.), wind power generation, information industry (hard drive, CD drive), consumer electronics (mobile phone, digital camera), household appliances (frequency conversion air conditioning, refrigerator and washing machine), elevator linear motor, magnetic separator, nuclear magnetic resonance imager, etc. The application of intelligent manufacturing, intelligent driving and intelligent service represented by robots remains to be developed. The Sintered NdFeB Trapezoid Magnets produced by YanHe Megtech are widely used in sensors and nuclear magnetic resonance imagers.
