Attributes of Ceramic Material
•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
•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 (1-8 possible)
•Grade 8 is the strongest ceramic material available
•Tooling can be expensive
