Alnico Ring Magnets
When a magnet is designed in a ring shape, a door to opportunity is unlocked. Alnico ring magnets have a circular shape and a hollow center, allowing them to be strung or threaded onto string, rod, or wire. Alnico ring magnets are desirable for their high residual induction, high energies, corrosion resistance, and for the fact that they have the widest temperature stability out of any standard magnetic material.
