The
AlNiCo magnet is belong to the
rare earth permanent magnet.
It was applied to many different fields.
It mainly have two classification, the
Cast AlNiCo magnet and
Sintered AlNiCo magnet.
AINiCo magnet is an alloy of
aluminum-nickel-cobalt, has excellent temperature stability and corrosion resistance, it can be used in motor, sensor, separator, Loudspeaker, holding system and so on.
Characteristic of
AlNiCo magnet:
1. High energies and relatively low coercivity.
2. Excellent ability to withstand extreme temperatures stability (as high as 500 ℃ , 930
oF)
3. High magnetic flux density, and resistance to demagnetization from vibration and shock.
4. Typical Applications for Alnico Magnets.
