Ferrites are non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite or magnetite as well as oxides of other metals.

Super strong arc/segment ferrite magnets:

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

Lower energy product than alnico and rare earth magnets

Most common grades of Y25, Y30, Y30H-1, Y30H-2, Y32, Y33 ceramic are 1, 5 and 8 (1-8 possible)
