The third generation of NdFeB is the best permanent magnet material at present. Custom shaped Neodymium magnets crystal (Nd2Fe14B) composed of iron (65%-75%), rare earth element neodymium (25%-35%), boron (1%) and a small amount of dysprosium, terbium, niobium, copper and other elements, can attract Compared with other permanent magnet materials, it has better mechanical properties and high temperature resistance. At the same time, the reserves of raw materials iron and rare earth neodymium are abundant and the price is low.
High-performance N52 grade magnet is defined as a sintered NdFeB permanent magnet material whose sum of intrinsic coercive force (Hcj) and maximum magnetic energy product ((BH)max) is greater than 60. Applications include new energy vehicles, wind power generation, frequency conversion Air conditioners, industrial motors, consumer electronics, intelligent manufacturing, etc. Low-performance NdFeB (Neodymium N35 or Neodymium N42) is mainly used in magnetic adsorption, magnetic separation, electric bicycles, luggage buckles, door buckles, toys and other fields. Magnets have disc, block, ring and countersunk magnets,
Sintered NdFeB magnet is widely used in voice coil motors (VCM), spindle drives due to their superior characteristics such as high magnetic energy product and high compaction density, which are in line with the development trend of miniaturization, light weight and thinning of consumer electronic products. Motors, mobile phone linear vibration motors, cameras, radios, speakers, headphones, digital telescopic lens motors and many other devices.
