Applications of Neodymium Magnets
As a kind of rare-earth permanent magnet material, NdFeB is full of excellent magnetic properties. The advantages of extremely high magnetic energy product, coercivity, and energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology, such as electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and aviation, etc. The more common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments.
However, the development of low-carbon economy such as new energy vehicles and wind power generation has put forward higher requirements on the magnetic properties of sintered NdFeB magnets. Magnets with high coercivity and high energy product have become an important trend in future development. High coercivity and high magnetic energy product have always been a contradiction, and the development of grain boundary diffusion technology has changed this phenomenon.
The use of grain boundary diffusion technology to control the composition and structure of the grain boundary of the magnet achieves the dual high comprehensive magnetic properties of high coercivity and high energy product, and reduces manufacturing costs and saves heavy rare-earth resources.
Neodymium iron boron materials (including Standard Sintered NdFeB and GBD Series) developed and manufactured by our company are widely used in various motors, such as brushless motors, stepper motors, servo motors, linear motors, permanent magnet synchronous motors, electric vehicles motors, etc. It provides more suitable sintered NdFeB materials for the rapidly developing global energy conservation and environmental protection industries, especially automation, electric vehicles, drones, robots, and energy-efficient home appliances.
We keep to researching and developing more suitable new magnetic materials, and improving the related working ablities in order to keep pace with the ever-changing future.
