Ceramic Magnet(Discs)

Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.

Ceramic (ferrite) magnets' Tolerances
For as pressed material, tolerance on the thickness (direction of magnetization) is 0.005. Other dimensions are 0 .010, whichever is greater. According to IMA standards, visual imperfections such as hairline cracks, porosity and minor chips are commonly found in sintered Ceramic (ferrite) magnets. A chipped edge is considered acceptable if no more than 10% of the surface is missing. Cracks are acceptable as long as they do not extend across more than 50% of pole surface.

Attributes of Ceramic Magnet
·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)
