Alnico Magnet is composed primarily of Aluminum, Nickel. Cobalt, Copper and Iron. It have very good corrosion resistence and high max working temperature, can reach 550deg C. Although other materials offer greater energy and coercivity values, the high remanence and thermal stability of Alnico makes it the most cost effective material for certain applications, like generator, microphone lifting, voltmeters and measuring instruments. It is widely applied in high stability fields as aerospace, military, automobiles and security
system.
