Excellent for High Temperature Applications Integrated Magnetics carries a large inventory of licensed, alnico magnetic materials in both standard & premium grades. Integrated Magnetics designs and builds custom alnico magnets, and magnetic assemblies, manufactured to meet your specialty requirements. Alnico magnets offer high magnetic remanence, and have much lower coercivities than the ceramic and rare-earth types of magnet materials. Part of the permanent magnet family, alnicos are less brittle than rare-earth magnets, and exhibit excellent temperature stability. They are manufactured through either a casting or sintering process, and can be made into complex shapes, which are not possible with some of the other magnet materials.
