Detailed information

The AlNiCo permanent magnet materials are composed primarily of aluminium, nickel, cobalt, iron, copper and titanium,AlNiCo is produced by castingsintering processes;

The casting process type AlNiCo magnets have better magnetic properties than sintering process type,but the manufacturing process of sintering AlNiCo magnets is simply.



Property:

In open magnetic circuit, the ration of length/diameter (L/D) of the AlNiCo magnets should be at least 4:1, with shorter length, Alnico magnets are very unstable;

AlNiCo magnets have good corrosion resistance characteristic; no coating is needed for surface protection;

AlNiCo magnets have the lowest Br temperature coefficient is -0.02%/°C and excellent stability over a wide temperature range;

The maximum operation temperature of AlNiCo magnets is 400℃ .


Application field:

AlNiCo magnet application newly developed is temperature-sensitive as hall-effect and MR-based automotive electronic sensors;

The traditional application are magnetron, TWT amplifiers, actuators, motors and Instrumentation;

In many applications they are being replaced by the rare earth permanent -magnets.
