Ceramic Magnet,Rings magnets,ceramic rings magnets

Ceramic (ferrite) magnets are are different from neodymium magnets and composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs ceramic magnets, rings ceramic magnets, blocks ferrite magnets, cylinders ferrite magnets, and sometimes arcs for motors.

Applications of speaker ring ferrite magnet

Attributes of Ceramic Magnet
·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
·Lower energy product than alnico and rare earth
·Most common grades of Y25,Y30,Y30H-1,Y30H-2,
Y32,Y33 ceramic are 1, 5 and 8 (1-8 possible)
