Al Nico

AlNiCo magnets are made by mixing aluminium, nickel and cobalt with iron and are particularly suitable for temperature sensitive applications. Al Nico is the first type of alloyed magnetic material and the oldest member of the magnet family (first developed in the early 1940's). Because of its excellent linear temperature characteristics, high magnetic flux density and good corrosion resistance, it is used for products of all sizes, from tiny cellular telephone magnets, weighing less than one gram, to radar focusing magnets weighing twenty kilograms or more.
