        Product details
        Y30BH Ceramic or Ferrite Block Magnets (F-001)

        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)
