NdFeB permanent magnet material, as the latest result of the development of rare earth permanent magnet materials, is called "Magnetic King" because of its excellent magnetic properties. The neodymium iron boron magnetic material is an alloy of niobium, iron oxide or the like. Also known as magnetic steel. NdFeB materials contain a large amount of barium and iron and are prone to rust. Therefore, the neodymium iron boron magnet must be surface coated.
Surface chemical blunt iron boronization is currently a good solution. NdFeB has a very high magnetic energy product and strength, and the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industrial and electronic technology, so that instrumentation, electroacoustic motor, magnetic separation magnetization It is possible to reduce the size, weight, and thickness of equipment. The advantages of NdFeB are high cost performance and good mechanical properties. The disadvantages are low Curie temperature, poor temperature characteristics, and easy chalking. It must be improved by adjusting its chemical composition and surface treatment. In order to meet the requirements of practical applications.
Sintered NdFeB permanent magnet materials have excellent magnetic properties and are widely used in electronics, electric machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. More common are permanent magnet motors, speakers, magnetic separators, Computer disk drive, magnetic resonance imaging equipment, etc.
Characteristics: NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound ND2Fe14B. The extremely high magnetic energy product and the strength, and the high energy density make the permanent magnet material widely used in modern industrial and electronic technology, so that the instrumentation, electroacoustic motor, magnetic separation magnetization and other equipment are miniaturized. Lightweight and thinner are possible.
