Do you know the advantages of NdFeB magnets?
NdFeB permanent magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. NdFeB has a very high magnetic energy product and coercive force, and can absorb a weight equivalent to 640 times its own weight. The advantages of high energy density make NdFeB permanent magnet materials widely used in modern industrial and electronic technologies, making it possible to reduce the size, weight, and thickness of instruments, electroacoustic motors, and magnetic separation magnetization.
NdFeB magnet advantages
The advantages of NdFeB magnets are high performance-price ratio, good mechanical properties and easy cutting. The disadvantages are low Curie temperature, poor temperature characteristics, and easy pulverization. The chemical composition and surface must be adjusted. The treatment method is improved to meet the requirements of the actual application.
NdFeB magnet advantages
The production of NdFeB is carried out by powder metallurgy process, and raw materials containing certain proportions such as ruthenium, osmium, iron, cobalt, ruthenium, osmium, aluminum, boron iron, etc. are smelted into alloy steel ingots by medium frequency induction melting furnace, and then crushed. The powder of 3 to 5 μm is pressed and formed in a magnetic field, and the formed green body is sintered in a vacuum sintering furnace to be dense and tempered, thereby obtaining a permanent magnet blank having a certain magnetic property. After the blank is subjected to grinding, drilling, slicing and other processing steps, the finished product of NdFeB is obtained by surface treatment.
