Neodymium-Iron-Boron (NdFeB) magnets are composed of neodymium, iron, boron and a few transition metals. These kind of permanent magnets are extremely strong and can be producted in different shapes and sizes (ie. arcs, blocks, discs, rings).
It has higher unit magnetic properties than other magnet and assure you of smaller size and lighter weight in designing devices.
3. Applications of Sintered NdFeB MagnetsThe 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.| · Automotive Starters | · Microphone Assemblies |
