Attributes of Ferrite Magnets :
High intrinsic coercive force
Tooling is expensive
Least expensive material compared to alnico and rare earth magnets
Limited to simple shapes 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 ferrite are 1,5 and 8 (1-8 possible)
Grade 8 is the strongest ferrite material available
