Product details
Ferrite Disc Magnets
General Description
Ferrite magnets are composed of strontium carbonate and iron oxide&period; They are charcoal gray in color and usually appear in the forms of discs&comma; rings&comma; blocks&comma; cylinders&comma; and sometimes arcs for motors&period;&period;&period;

Attributes&colon;
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&comma; 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&comma; 5 and 8 &lpar;1 to 8 possible&rpar;
Grade 8 is the strongest ceramic material available&period;
Applications&colon;
Application ranges include speaker magnets&comma; DC brushless motors&comma; magnetic resonance imaging &lpar;MRI&rpar;&comma; magnetos used on lawn mowers and outboard motors&comma; DC permanent magnet motors &lpar;used in cars&rpar;&comma; separators &lpar;separate ferrous material from non-ferrous&rpar;&comma; magnetic assemblies designed for lifting&comma; holding&comma; retrieving and separating&period;&period;&period;
