Measurements:

AlNiCo magnets have a high remanence, but a fairly low coercivity. This means the AlNiCo magnetic material has a high flux density which, however, is only hardly present in the magnet and can easily be weakened by demagnetising influences. For this reasons AINiCo rod magnets should not be stored or used with equal poles opposing each other (repelling).
In temperatures ranging from - 270 °C up to + 400 °C AINiCo is very stable. Its temperature coefficient is as low as - 0.02% per degree C.
A high nickel content of the alloy results in good stability against most acids and against oxidation.
  Most AlNiCo magnets are used for operating magnetic switches (reed switches). The magnet lengths should correspond to the length of the glass housing of the reed switch, with parallel arrangement of switch and magnet.
