Alnico magnets are permanent magnets constructed from aluminium, nickel and cobalt. These strong magnets are typically less brittle than most rare-earth magnets and can be magnetised to produce a strong magnetic field.
First4magnets.com stocks a small range of red epoxy painted high quality alnico magnets. Our alnico magnets are available in a range of different shapes and sizes.
Alnico magnets have been in production since the early 1930’s and predated the discovery and manufacturing of almost all rare-earth magnets. While alnico magnets have largely been replaced by stronger rare-earth magnets they are still commonly used in the manufacturing of sensors, guitar pickups, loudspeakers and many other everyday household objects.
