Flexible Neodymium Magnet
Production Process of Flexible Neodymium Magnet
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 NdFeB Flexible 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 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 an efficiency better than compression molded ring magnet.
-
Dispensing with mold, short downtime.
-
Applicable temperature: -40℃～120℃;
-
After systematic reliability inspection, it is consistent and reliable.
-
Can be made into different shapes such as long strips, slim strips, rings, pore plates, large sheeting, etc. to meet different requirements.
