Alnico Rectangular Magnets


We stock Alnico Rectangular 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 rectangular magnets should have a length to equivalent diameter ratio of about 4 to 1 in order to avoid self-demagnetization.
