5 NdFeB magnetic energy can be for how long? NdFeB magnets has a very high coercivity demagnetization and magnetic changes do not appear the most reliable mold magnet, the magnetic field of the natural environment and general condition. Assume appropriate environment, even after prolonged use, the most expensive mold magnet magnet magnetic loss will not be great. So in practice, the mold magnet, we tend to ignore the impact of time on the magnetic properties. 6 on alignment directions direction: anisotropic magnet can get the best direction is called magnetic direction of magnetic orientation. Magnet into an isotropic magnets: are the same in any direction of the magnetic anisotropy of the magnet 2 magnets: magnetic properties will be different in different directions; and there is a direction that is oriented direction, the lowest price mold magnets oriented in the direction The resulting magnetic properties when the highest magnet. Sintered NdFeB magnets are anisotropic, which in pre-production needs to determine the orientation direction (magnetization direction). Magnet Manufacturer: NdFeB How made? Sintered NdFeB powder metallurgy manufacturing process is an iron-based permanent magnet material. The main steps are: formula, melting, milling, molding orientation, sintering, machining, plating processing. Control wherein the oxygen content is an important indicator of the level of workmanship. The new production plant Tong Company has selected high-vacuum melting, sintering furnace and advanced automatic control jet mill, to ensure that the basic production process anaerobic operation, so that product performance and temperature are breakthrough improvements.
