NdFeB magnets -The Strongest Permanent Magnets Today
Neodymium-Iron-Boron (NdFeB) magnets are composed of neodymium, iron, boron and a few transition metals. It is used most popular by people in industry and our daily life. These kind of permanent magnets are extremely strong and can be producted in different shapes and sizes (ie. arcs, blocks, discs, rings).

2. Applications of Sintered NdFeB Magnets
The permanent magnets, which are called the next centurial magnets, are used in a wide range of industries including computer, automobile, electric machinary, electro-sound devices, automatic control, magnetic force mechanism, microwave commnication, petrochemical industry, medical apparatus and equipment. The magnets are the ideal materials for the subminiature magnetic devices with high function.NdFeB magnets is especially suitable for developing those new products demanding high quality, small volume and light weight.
