Alnico
Rod Magnets
We stock Alnico Rod magnets in both Grade 5 and
Grade 8. Alnico 8 magnets have a lower remanence,
but a higher coercivity than Alnico 5 magnets. This means that Alnico
5, though stronger in the right circumstances, is easier to demagnetize.
Alnico 5 rod magnets should have a length to diameter ratio of about 4
to 1 in order to avoid self-demagnetization.
