Alnico Magnets

Alnico magnets have been a mainstay of the industry since the 1930s. They are composed of aluminum, nickel, and cobalt, and available in both cast and sintered forms. The key benefits of Alnico magnets include temperature stability (over 500°C with no permanent magnetic loss), ease of demagnetization and high corrosion resistance. Alnico magnets exhibit high Br, but low Hc. Their energy product range is approximately 1.4-11 MGOe.
