Alnico magnets are made up of a composite of aluminum, nickel and cobalt with small amounts of other elements added to enhance the properties of the magnet. Alnico magnets have good temperature stability, good resistance to demagnetization due to shock but they are easily demagnetized. Alnico magnets are produced by two typical methods, casting or [...]
Cast AlNiCo Manufacturing Process Alnico magnets are manufactured either by casting or sintering. Alnico is produced by conventional foundry methods using resin bonded sand molds or powder metal manufacturing methods. Sintering Alnico is suitable for complex geometries. Most Alnico produced is anisotropic meaning that the magnetic axle of the grains is oriented in one direction. The [...]
