Magnetic materials - Part 1: Classification

Magnetic materials - Part 1: Classification

Intended to classify commercially available magnetic materials. The term "magnetic materials" denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties. The classification of magnetic materials is based upon the generally recognized existence of two main groups of products. - soft magnetic materials (coercivity less than or equal to 1000 A/m) - hard magnetic materials (coercivity greater than 1000 A/m) Within these main groups, the classification when appropriate recognizes the following characteristics: - the main allowing element and the metallurgical state and physical properties of the material; - when possible and convenient, the relationship between these characteristics is identified. A classification by specific areas of application cannot be applied to all materials because different materials can very often be used for the same application depending on the characteristics required.

Matériaux magnétiques - Partie 1: Classification

Pour objet la classification des matériaux magnétiques disponibles commercialement. Le terme "matériaux magnétiques" décrit les substances dont l'application exige l'existence de caractéristiques ferromagnétiques ou ferrimagnétiques. La classification des matériaux magnétiques est basée sur l'existence généralement reconnue de deux groupes principaux de produits: - les matériaux magnétiques doux (coercivité inférieure ou égale à 1000 A/m) - les matériaux magnétiques durs (coercivité plus grande que 1000 A/m). A l'intérieur de ces groupes principaux, la classification reconnaît lorsque cela est approprié les caractéristiques suivantes: - l'élément principal d'alliage et l'état métallurgique et les caractéristiques physiques du matériau; - lorsque cela est possible et réalisable pratiquement, la relation entre ces caractéristiques est identifiée. Une classification selon les domaines spécifiques d'application ne peut être appliquée à tous les matériaux, car différents matériaux peuvent bien souvent être utilisés pour la même application en fonction des caractéristiques requises.

The specified property is measured at an ambient temperature of (23 ± 5) °C both without heat treatment and after heat treatment.
This edition includes the following significant technical changes with respect to the previous edition:  
the method of test for adhesion has been modified to match to the method of bend test specified in ISO 1519 using a cylindrical mandrel of 32 mm in diameter instead of the 30 mm diameter mandrel specified in the first edition;
the method of test for interlaminar insulation resistance has been modified to match to the method specified in IEC 60404-11 and the modified Franklin test has been removed;
the method of test for compressibility has been modified to match to the method of test for stacking factor specified in IEC 60404-13;

IEC TR 63304:2021(Main)
Methods of measurement of the magnetic properties of permanent magnet (magnetically hard) materials in an open magnetic circuit using a superconducting magnet

IEC TR 63304:2021(E) describes the general principle and technical details of the methods of measurement of the DC magnetic properties of permanent magnet materials in an open magnetic circuit using a superconducting magnet (SCM).
This method is applicable to permanent magnet materials, such as those specified in IEC 60404-8-1, the properties of which are presumed homogeneous throughout their volume.
There are two methods:
– the SCM-Vibrating Sample Magnetometer (VSM) method;
– the SCM-Extraction method.
This document also describes methods to correct the influence of the self-demagnetizing field in the test specimen on the demagnetization curve measured in an open magnetic circuit. The magnetic properties are determined from the corrected demagnetization curve.
NOTE These SCM-methods can determine the magnetic properties of permanent magnet materials with coercivity higher than 2 MA/m. The methods of measurement in a closed magnetic circuit specified in IEC 60404-5 can lead to significant measurement error due to saturation effects in the pole pieces of yoke for the magnetic materials with coercivity higher than 1,6 MA/m (see IEC 60404-5).

IEC 60404-8-7:2020 defines the grades of cold-rolled grain-oriented electrical steel strip and sheet in nominal thicknesses of 0,20 mm, 0,23 mm, 0,27 mm, 0,30 mm and 0,35 mm. In particular, it gives general requirements, magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures. This document applies to Goss textured grain-oriented electrical steel strip and sheet supplied in the final annealed condition in coils or sheets, and intended for the construction of magnetic circuits. The grades are grouped into three classes:
- conventional grades;
- high permeability grades;
- magnetic domain refined high permeability grades.
They correspond to Class C22 of IEC 60404-1.
This edition includes the following significant technical changes with respect to the previous edition:
- insertion of a third class of grain-oriented electrical steels for magnetic domain refined high permeability grades;
- introduction of the single sheet tester (SST) method as reference measurement method for this third class of material together with a conversion factor for transposition of the SST measurement results to equivalent Epstein values;
- update of the electrical steel range to take account of the current offers and demands of grades.
