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.
Material Information
- Production by casting or powder metallurgical techniques An alloy composed of a matrix of Al-Ni-Fe-Co
- Excellent stability over a wide temperature range higher than 500°C
- Strong corrosion resistance capability without coating for surface protection
- Good resistance to demagnetization from vibration and shock
- Good flux density at a reasonable cost
- Very hard & brittle
