Flexible Neodymium Magnets
Production Process of Flexible Neodymium Magnets
NdFeB Flexible Magnet is composed of melt-spun NdFeB powder and rubber.
Thickness: 0.5~8.0 mm
Length: as per your requirement.
Magnetization: multi-poles or through the thickness
Surface treatment: UV-coated or Patterned
Characteristics of Flexible Neodymium Magnets
- The strongest isotropic flexible magnet in the world so far, a Max. BH of 90KJ/m3(11.25MGO) is available at the laboratory, an amazing 5 times more than that for a Ferrite magnetic strip, quite close to the highest property of compression Molded NdFeB ring magnet, magnetic property for industrial batch quantity ranges from 16 to 68 KJ/m3(2.0-8.5MGO).
- Outstanding flexural strength can be automatically assembled, with better efficiency than compression molded ring magnet.
- Dispensing with mold, short downtime.
- Applicable temperature: -40℃～120℃;
- After systematic reliability inspection, it is consistent and reliable.
- It can be made into different shapes such as long strips, slim strips, rings, pore plates, large sheeting, etc. to meet different requirements.
