Magnetic materials - Part 8-1: Specifications for individual materials - Magnetically hard materials

IEC 60404-8-1:2023 specifies minimum values for the principal magnetic properties of, and dimensional tolerances for, technically important permanent magnet (magnetically hard) materials.
For information purposes only, this document provides values for the densities of the materials and the ranges of their chemical compositions.
This fourth edition includes the following significant technical changes with respect to the previous edition:
a) recently developed anisotropic REFeB hot deformed magnets and anisotropic HDDR REFeB bonded magnets are included;
b) high energy Ca-La-Co ferrites stabilized by La and Co substitution are included;
c) new and high-performance grades of REFeB and RE2Co17 sintered magnets and isotropic REFeN bonded magnets are added.

Magnetische Werkstoffe – Teil 8-1: Anforderungen an einzelne Werkstoffe – Hartmagnetische Werkstoffe (Dauermagnete)

Matériaux magnétiques - Partie 8-1: Spécifications pour matériaux particuliers - Matériaux magnétiquement durs

L'IEC 60404-8-1:2023 spécifie les valeurs minimales des principales propriétés magnétiques et les tolérances sur les dimensions pour les matériaux (magnétiques durs) pour aimants permanents qui présentent un intérêt technique important.
Le présent document fournit uniquement des valeurs indicatives pour les masses volumiques des matériaux et leurs plages de compositions chimiques.
Cette quatrième édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) ajout des aimants déformés à chaud REFeB anisotropes et des aimants agglomérés REFeB HDDR anisotropes récemment développés;
b) ajout des ferrites Ca-La-Co à haute énergie stabilisés par substitution de La et de Co;
c) ajout de nouvelles qualités et de qualités hautes performances pour les aimants frittés REFeB et RE2Co17 et les aimants agglomérés REFeN isotropes.
