EspañolThe sintering temperature has a significant effect on the microstructure and magnetic properties of segmented NdFeB magnets.
Segmented NdFeB magnets are made of hard magnetic materials and soft magnetic materials with certain magnetic properties arranged in a specific arrangement. During sintering, the small segments are bonded together by heating under pressure to form a solid magnet.
The sintering temperature affects the formation of magnet microstructure, including grain size, grain boundary structure and crystal texture. High sintering temperature can lead to larger grain size and reduced grain boundary area, which can lead to improved magnetic properties such as coercivity and remanence. However, too high sintering temperature will cause the magnetic properties of the magnet to decrease due to grain growth and porosity increase.
In addition, NdFeB magnet manufacturers indicate that the sintering temperature also affects the magnetic anisotropy of the magnet. A high sintering temperature promotes the development of a preferred crystal structure, which is essential to achieve a high degree of magnetic anisotropy in magnets.
In summary, the sintering temperature plays a crucial role in determining the microstructure and magnetic properties of segmented NdFeB magnets. Optimum sintering temperature can improve magnetic properties such as higher coercivity, remanence and maximum energy product. Therefore, the sintering temperature must be carefully controlled when producing segmented NdFeB magnets.
The tile neodymium iron boron magnet is named after its extremely similar shape to the tile, and more than one-third of its output is used to manufacture various permanent magnet motors. Permanent magnet motor has the advantages of electricity saving, electricity saving, light weight, small size, high specific power. Electric bicycle motors, computer driven motors, lathes, etc. are used to measure the speed and rotation speed of motors, elevator traction motors, refrigerator air conditioning motors, wind turbines, automobile motors, etc., which are widely used.
The Sintered NdFeB Magnet is powerful permanent magnet in modem times. It is not only has excellent properties such as high remanence, high coerce, high magnetic energy product .high performance price ratio and so on,but also is development of high-performance,miniaturized and lightweight replacement products.
