Ferrite (Ceramic) Magnets

Ferrite is the lowest cost magnet material currently available, which may be why sintered ferrite magnets are used in automotive small motor applications as well as in many other consumer products. Composed of Strontium Ferrite, these hard, brittle materials stand up well to demagnetization, except in extreme cold environments. Ferrite has an approximate energy product range of 1.1-4.5 MGOe.
