Applications of Ceramic Magnets
- Speaker magnets
- DC brushless motors
- Magnetic Resonance Imaging (MRI)
- Magnetos used on lawnmowers and outboard motors
- DC permanent magnet motors (used in cars)
- Separators (separate ferrous material from non-ferrous)
- Used in magnetic assemblies designed for lifting, holding, retrieving and separating
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
