Product description

Aluminium-Nickel-Cobalt or AlNiCo magnets are used less nowadays, having been mostly replaced by stronger rare-earth magnets. However, AlNiCo is still used in the manufacture of sensors, guitar pickups, relays and alternators. AlNiCo magnets play an especially crucial role in all electropermanent magnetic switches and lifting magnets. This is due to the low resistance to demagnetization – and being remagnetized: if electric coils are wound around AlNiCo magnets, they can easily switch on and off magnetically.
