Ferrite

Ferrite magnets are more commonly referred to as ceramic magnets. They are mostly composed of strontium and Iron oxide (SrO . 6Fe2O3) and offer solid performance with their low cost, higher coercive force than alnico and low recoil permeability. They are widely used for loudspeakers, small motors, generators, and rotors.

Hitachi Metals America, Ltd. (HMA) offers a complete line of ceramic magnets.

Characteristics
