Alnico Magnets (Sintered and Cast) As an alloy of aluminum-nickel-cobalt, Alnico magnets are widely used due to the superior temperature stability and high influx density. There are two types of Alnico Magnets produced by LIHE, sintered and cast. Alnico Magnets with complex shapes are always produced by cast. Alnico describes a family of materials that possess excellent temperature stability, high residual induction, and relatively high energies. The alloy is derived from a common base composition comprised of aluminum, nickel, cobalt, and iron, with varying proportions of other elements. Alnico alloys possess the lowestreversible temperature coefficient of any permanent magnet material. The high nickel content of alnico results in good resistance to corrosion and oxidation, and this material is also a good electrical conductor. Cast alnico may be manufactured in many shapes and sizes not possible with other magnet materials. Parameter: Value.

Alnico-Magnete werden aus einer Legierung aus Aluminium (Al), Nickel (Ni) und Kobalt (Co) sowie Eisen, Kupfer und Titan in zwei unterschiedlichen Methoden gefertigt ; entweder im Guß-Verfahren oder im Sinter-Verfahren. Dadruch können die verschiedensten Formen hergestellt werden. Alnico-Magnete werden daeingesetzt, wo bei hohen Temperaturschwankungen ein konstantes Magnetfeld gebraucht wird. Alnico-Magnete können in Temperaturbereichen von -270°C bis über +400°C eingesetzt werden. Cast Alnico magnet, which are aluminum nickel-cobalt-iron alloys, are the most established and widely used permanent materials. Because of its excellent stability over a wide temperature range, high flux density at a reasonable cost. Alnico magnet have been accepted in the widest range of application. Alnico magnet is very suitable for using in Strong Speakers, telephones, mobile, odometer, electricity meter, water meter and sensors. Sintered alnico is usually restricted to smaller sizes and offers slightly lower magnetic properties, but has tighter dimensional tolerances due to its processing.
