Sintered /Casted AlNiCo Magnets

Sintered /Casted AlNiCo Magnets

Summarize:

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 400C.
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.
