Applications of Neodymium magnet: Sintered NdFeB permanent magnetic material has excellent magnetic properties, widely used in electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and aviation, etc. The more common ones are permanent magnetic motors, loudspeakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment instrumentation and so on. Nano (Royce3010) chelate film without plating treatment can meet the marine climate conditions in the use of 20-30 years, can be widely used in sea-based wind power generation. Surface adhesion of more than 20Mpa, can be widely used in permanent magnet high-speed motors, special motors, electric vehicle motors, ultra-high voltage, high-voltage DC power supply system, fast charging system, aerospace and military industries and other fields.
