on Magnet materials • Alnico Magnets Alnico magnet alloy is largely comprised of Aluminum‚ Iron‚ Cobalt and Nickel. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content. Alnico magnet alloy has high maximum operating temperature and a very good corrosion resistance. Some grades of Alnico alloy can operate upwards of 1000C. Magnets made with this alloy are available in a variety of grades and dimensions and they are usually cast. Alnico magnet material is an older
