Flexible NdFeB Magnet Sheet

Product Details

Flexible NdFeB magnet is a new type of flexible magnetic material. The material consists of neodymium (NdFeB) powder dispersed in plastic, flexible carrier, production process is calendaring or extrusion.
Flexible NdFeB magnet can be magnetized in many ways (most magnetization are one side multipolar and axial magnetization). The material is much stronger than standard magnetic foil and has higher working temperature 120 ℃.
The main advantage to sintered magnets (Ferrite, Neodymium) is better workability and its flexibility - Flexible NdFeB magnet can be cut, drilled, milled. Magnetic parameters are between sintered Ferrite and neodymium magnets. Flexible NdFeB 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.

Characteristics

• The highest magnetic properties in isotropic flexible magnet, (BH)max=10.0MGO in lab and (BH)max =2.0-8.5 MGOe in mass production.
• Working temperature ranges from -40℃to120℃

• Good stability and reliability, which have been proved by systemic testing

• Shorter production process without any mould

• Various shapes: long and narrow bars, large area thin sheets, thin ring, etc.

• Good flexible properties, virtually no cracking,no chipping(No cracks on the magnet when 1 mm thick sheet was wrapped around 10 mm diameter mandrel).

• Flexible magnetizing, low cogging due to magnetically isotropic characteristics.
