Disc Ferrite Magnet, Available in Various Shapes, High Intrinsic Coercive Force
General description:
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
Attributes:
Affordable 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 magnets
Finishing requires diamond cutting or grinding wheel
Lower energy product than alnico and rare earth magnets
Most common grades of ceramic are 1, 5 and 8 (1 to 8 possible)
Grade 8 is the strongest ceramic material available
