Sintered Hard Ferrite
Magnet,
Hard Ferrite Magnet,
Ceramic Magnet
Ceramic (ferrite) magnets are composed of
strontium carbonate and iron oxide. Ferrite
Magnets are charcoal gray in color and
usually appear in the forms of discs, rings,
blocks, cylinders, and sometimes arcs for
motors.
-
Least expensive material compared to alnico and
rare earth magnets
-
High intrinsic coercive force
-
Available in simple shapes only due to
manufacturing process
-
Lower service temperature than alnico, greater
than rare earth
-
