• High intrinsic coercive force
• Tooling is expensive
• Least expensive material compared to alnico and rare earth magnets
• Limited to simple shapes 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
