Cast Alnico magnet is composed primarily of Aluminum, Nickel, Cobalt, Copper, and Iron. It has very good corrosion resistance and high-temperature operation.
Although other magnetic materials offer greater energy and coercivity values, the high remanence and thermal stability of AlNiCo make it the most effective magnetic material for certain applications, like generators, microphones, lifting, voltmeters, and measuring instruments. It is widely applied in high-stability fields like aerospace, military, automobile, and security systems.
