Ferrite | Ceramic Magnets
Ferrite (Ceramic) Magnets provide real value because they are inexpensive, moderate in magnetic strength, and they are easily magnetized in a variety of formats. Ceramic magnets offer good corrosion resistance and do not require a coating or plating. They are able to withstand heat reasonably well and can often be found in automotive and engine applications among many others. The maximum operating temperature for a ceramic magnet is 250°C. Operating a ceramic magnet above 250°C will begin to result in magnetic strength losses. Operating ceramic magnets in extreme cold (below -20°C) will also result in temporary to permanent losses.
