Product Description

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
• The 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

Product Description



Sintered Ferrite(Ceramic) Magnets developed in the 1960s as a low-cost alternative to metallic
magnets. Although they have low energy (compared with other permanent magnet materials) and are
relatively brittle and hard, Ceramic Magnets (Hard ferrite magnets) have won wide acceptance due to
their good resistance to demagnetization, excellent corrosion resistance, and low price per pound. In
fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption.
It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging
and automotive sensors.
