AlNiCo magnets

AlNiCo magnets are alloys of Fe, Al, Ni, Co, Cu and Ti.
Like neodymium magnets, they have a high residual magnetization Br, but much lower coercive force Hc and magnetic energy (B.H)max.
The presence of cobalt, nickel and titanium in the composition makes them more expensive than neodymium and many times more expensive than ferrite magnets.
The main advantages of AlNiCo over all other magnets are their stable magnetic characteristics over time, which are least affected by temperature changes. AlNiCo magnets can be used at temperatures up to 500°C. These qualities make them indispensable in measuring instruments, precision acoustic transducers, sensors and other devices requiring parameters that are stable over time and temperature changes.
