标准摘要
[中文适用范围]： 本部分 IEC 60404 规定了技术上重要的永磁（磁硬）材料的主要磁性能的最小值和尺寸公差。 本文件仅提供材料的密度值和其化学成分范围的信息。 注：表 A.1 中提供了有关磁性材料的一些附加物理数据和机械参考值，以供信息和比较之用。 [外文原描述]： 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.
