The magnet which consists of various metallic alloys of aluminium, nickel and cobalt. Alnico magnets, which are one of the first high induction magnets, are used in stimulation of installation for electric machine magnets.

Cobalt is very expensive because it is a rarely found element, and, because of it’s coercive field volume, it is not preferred in magnetic machine design.

It’s practicality at high temperatures and it’s endurance with it’s structure (impact, smash), compared to other magnets, are the cause of preference.
