Product Description

Ferrite Disc Magnets
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:
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 to 8 possible)
Grade 8 is the strongest ceramic material available.
Applications:
Application ranges include speaker magnets, DC brushless motors, magnetic resonance imaging (MRI), magnetos used on lawn mowers and outboard motors, DC permanent magnet motors (used in cars), separators (separate ferrous material from non-ferrous), magnetic assemblies designed for lifting, holding, retrieving and separating.For more detail info, please feel free to visit our website or inquire us at any of your convenience.ParametersMarkUnitValueRecoil PermeabilityUrce-1.05-1.3Curie TemperatureTc°c460The temperature of BraBr°c -1-0.2%The temperature of HcjaHcj°c -10.2-0.5%DensityDg/cm 34.5-5.1ResistivityPΩcm≥10 4The coefficient of linear expansionaR°c -17 -15x 10 -6 HardnessHV-480-580
