General Information

Alnico magnet material is an alloy of aluminum -nickel-cobalt with minor amounts of other elements such as titanium and copper. Alnico magnets are characterized by excellent temperature stability over a wide temperature range and high residual induction. They are a candidate for continuous duty applications where temperature extreme up to 500°C can be expected. However, the coercive force and maximum energy product are not high. They limit their applications in many cases. Casting and sintering are two major processes used to manufacture the Alnico magnets. Alnico magnets with complex shapes may be manufactured by casting.
