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.

All standard magnets are supplied magnetised parallel to the length.

The following standard magnets are generally available at short notice from stock. Circular rod magnets with other dimensions in the diameter range from 3 to 20 mm are available for large series production. All dimensions in mm.

AlNiCo 500 corresponds to AlNiCo 35/5 according to DIN 17410 or ICE 404-8-1. We can also supply other AlNiCo alloys for large series production.
