Sintered Neodymium Magnet is a type of magnetic-alloy-compound made of neodymium-iron-boron. It is widely used in many applications due to its reasonable price, stable magnetic performance, high magnetic flux density and excellent corrosion resistance. It is made from a magnetic-alloy-compound with special heat treatment, which results in a more stable and powerful magnetic field. Its magnetic field is up to 10 times stronger than most other magnets. It is widely used in motors, generators, electromechanical devices, medical equipment, instrumentation, and other industries.
