Share to:

1.25*18*4 ferrite magnetic
2.Material:Ferrite Permanent Magnet
3.Certificate:ISO9001,CE,ROHS,SGS
4.Attractive in price and quality

Attributes

>>1 Least expensive material compared to alnico and rare earth magnets

>>2 High intrinsic coercive force

>>3 Available in simple shapes only due to manufacturing process

>>4 Lower service temperature than alnico, greater than rare earth

>>5 Finishing requires diamond cutting or grinding wheel

>>6 Lower energy product than alnico and rare earth magnets

>>7 Most common grades of ceramic are 1, 5 and 8 (1-8 possible)

>>8 Grade 8 is the strongest ceramic material available 9. Tooling can be expensive
