AlNiCo magnets are composed mainly of aluminum, nickle,
cobalt and iron with varying additions of other elements including
copper and titanium. By varying the composition it is possible to
tailor the magnetic properties to meet the needs of a wide variety
of end use applications.

AlNiCo alloys, which possess the lowest reversible temperature
coefficient magnetism in permanent magnet materials, have
excellent working temperature up to 550 centigrade. High nickel
content of AlNiCo alloy results in good stability against corrosion
and oxidation, this metallic composition is also a good electrical
conductor.
