Sintered NdFeB
NdFeB is a new type of permanent magnet material developed since 1983. It has extremely high magnetic properties, is widely used in various fields such as permanent magnet motors, engineering machinery, electro acoustics, electrical appliances and medical devices.
Our company has advanced equipment such as VFS vacuum sintering furnace, alpine vacuum air mill, hydrogen breaking pulverizing and imported press, which can produce high-performance NdFeB products of N54,N52H,N50SH,N45UH,N38EH, with an annual output of 2000 tons.
