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 magnets

Most common grades of Y25, Y30, Y30H-1, Y30H-2, Y32, Y33 ceramic are 1, 5 and 8 (1-8 possible)
