China Ceramic Magnets
Ferrite (ceramic) magnets (Hard
ferrite magnet) were developed in the 1960's
as a low cost alternative to metallic
magnets. Even though they exhibit low energy
(compared with other permanent magnet
materials) and are relatively brittle and
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.
-
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
-
