The advantages of AlNiCo magnets are high remanency (up to 1.35T), but the disadvantages are very low coercivity (usually less than 160kA/m) and nonlinear demagnetization curve, so AlNiCo magnets are easy to be magnetized and also easy to demagnetization.

In the permanent magnet materials, the cast AlNiCo magnet has the lowest reversible temperature coefficient. AlNiCo magnet has good temperature stability and aging stability, and is suitable for making instruments, motors, electroacoustic devices, magnetic machinery and so on.
