Material information

Useful information

AlNiCo magnets are metallic alloy magnets made of aluminum, nickel, cobalt, iron, copper, titanium and chromium.

They are produced by sand casting, chill casting, vacuum precision casting and sintering.

AlNiCo magnets are characterized by high remanences and small temperature coefficients and are therefore used where a constant magnetic field is required despite larger external temperature fluctuations. Compared to the new magnetic materials AlNiCo magnets have a low coercivity.

The high nickel content in the alloy results in a high resistance against most acids and against oxidation.
