Features of TDK's magnets
Ferrite Magnets FB Series
A oxide magnet made by sintering, using advanced
fine powder control technologies based on a powder
metallurgy method. Not susceptible to weakened magnetic fields, this is our core magnet product with outstanding properties for practical applications that surpass those of conventional metal magnets. Another
strong feature is that it can be produced in volume at
costs significantly below neodymium magnets.
