AlNiCo
Our AlNiCo productsAlnico®
Our AlNiCo materials are manufactured using a casting procedure. In this procedure, the metal alloy (aluminum, nickel, cobalt, iron) is cast in the required shape and is then subject to a number of heat treatment stages. These products acquire their anisotropic properties by means of annealing in the magnetic field. These materials are very brittle and can only be machined by means of grinding or erosion.
AlNiCo magnets are characterized by a high level of remanence and can be used at temperatures of up to
450°C.
450°C.

The maximum operating temperature for a magnet matrials is dependent upon the specific application and magnet geometry. Do not hasitat to contact our Application Engineers for more information. Die maximale Einsatztemperatur ist abhängig von der Anwendung, von der Magnettype sowie der Magnetgeometrie. Für weitere Informationen kontaktieren Sie bitte unsere Anwendungstechniker. La température maximale d'utilisation d'un aimant dépend de son application spécifique ainsi que de sa géométrie. N'hésitez pas à prendre contact avec nos ingénieurs d'application pour plus d'informations. |
