Sintered Neodymium Magnet is a kind of high performance rare earth permanent magnet made of powder metallurgy. It is made by mixing the neodymium iron boron powder and other additives, pressing them into a certain shape, sintering and magnetizing. It can have strong magnetic properties and can reach high working temperatures up to 80-220°C. It has high coercivity, high performance and low cost, and can be used in various applications such as new energy cars, wind power generation, servo motors, traction motors and so on.
Sintered Neodymium Magnet has a wide range of grades, from N35-N52, 35M-50M, 35H-48H, 30SH-45SH, and can be customized according to customers' magnetic orientation requirements. Different coatings, such as Nickel, NiCuNi, Zinc and Epoxy, can also be selected according to customers' needs.
The main advantages of Sintered Neodymium Magnet include high stability, uniform magnetic properties, high-temperature resistance, corrosion resistance and strong adsorption force. These features make it the ideal choice for high-end powder metallurgy magnets, neodymium iron magnets and powder metallurgy magnets.
