Product Description

Product Description

•  Product Info

  Neodymium (NdFeB) permanent magnet is composed of neodymium, iron, boron and a few transition metals. It has many advantages like high coercive force, high energy, high performance/ cost ratio and can be easily formed into various shapes and widely used in many fields such as aviation, electronics, instruments, meters, DC motors, Liner motors, MRI, medical and health products. It is the third generation of rare earth permanent magnet and at the same time the most powerful and advanced commercialized permanent magnet today.
