Description
NdFeB magnet material, as the latest result of the development of rare earth permanent magnet materials, is known as "Magnetoking" because of its excellent magnetic properties. NdFeB magnetic material is an alloy of neodymium, iron oxide, etc. Also known as magnet. NdFeB has extremely high magnetic energy product and correction force, and the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology, so that instrumentation, electroacoustic motors, magnetic separation magnetization and other equipment miniaturization, lightweight, thinning is possible. The advantages of NdFeB are high cost performance and good mechanical properties; The disadvantage is that the Curie temperature point is low, the temperature characteristics are poor, and it is easy to pulverize and corrode, and it must be improved by adjusting its chemical composition and adopting surface treatment methods to meet the requirements of practical applications.
