Casted Ring Shape AlNiCo Magnets

Cast magnets may be manufactured in complex shapes, such as horseshoes, not possible with other magnet materials. Sintered Alnicos offer slightly lower magnetic properties but better mechanical characteristics than cast Alnicos. Cast Alnico5 is the most commonly used of all the cast Alnicos. This material is used extensively in rotating machinery, meters, instruments, sensing devices, and holding applications.

Casted Ring Shape AlNiCo Magnets

Alnico magnets are electrically conductive, unlike ceramic/ferrite magnets. To their advantage, alnico ring magnets though still brittle are typically less brittle than most rare-earth magnets and produce a strong magnetic field. They can also operate at the highest temperatures of any magnetic material, keeping their magnetism even when red hot! However, they are more easily demagnetized than ceramic or rare earth magnets.
