Product Description:
Sintered Neodymium Magnet is a kind of permanent magnet made of
Neodymium Iron Boron (NdFeB) material. It's the most powerful type
of permanent magnet, which is widely used in many applications,
such as motors, generators, sensors, and loudspeakers. The magnet
has strong magnetic properties and a wide range of available
shapes, sizes, and grades, including N35-N52, 35M-50M, 35H-48H,
30SH-45SH, etc. It can also be provided with different kinds of
coating, such as Nickel, NiCuNi, Zinc, Epoxy, etc. Moreover, it has
high resistance to demagnetization and can be used in a wide range
of working temperatures, from 80 to 220°C. In addition, customized
shapes of Sintered Neodymium Magnet are available, such as blocks,
arcs, rings, etc.
