The above mentioned magnet grades are but a few of the sintered ferrite grades available from Polaris REM. Sintered Ferrite magnets are anisotropic in nature. They are the lowest cost and most corrosion resistant magnet material. Sintered Ferrite magnetic properties are lower than those of isotropic bonded NdFeB magnets. Please contact PolarisREM with your specific requirements.
