Neodymium rubber magnet is a new type of flexible magnetic material. The material consists of neodymium (NdFeB) powder dispersed in plastic, flexible carrier, production process is calendering or extrusion.
Neodymium rubber magnet can be magnetized in many ways (most commonly used magnetizations are one side multipolar and axial magnetization). This material is much stronger than standard magne-tic foil and has higher working temperature 120 ℃.
The main advantage to sintered magnets (ferrite, neodymium) is better workability and its flexibility - neodymium rubber magnet can be cut, drilled, milled. Magnetic parameters are between sintered ferrite and neodymium magnets. Neodymium rubber magnet can replace hard ferrite magnets thanks to magnetic parameters while brings the advantages of rubber material - flexibility and workability. Main application areas are: flat speakers, sensors, miniature motors.
