EN 10331:2003 - Magnetic materials - Specification for sintered soft magnetic materials

Overview

SIST EN 10331:2003 is a European Standard developed by CEN that specifies the magnetic and mechanical properties of sintered soft magnetic materials. These materials are utilized exclusively for components produced via powder metallurgical processes. The standard excludes magnetically soft castings and semi-finished products, focusing on sintered metals with optimized characteristics for soft magnetic applications.

This document provides essential requirements concerning the manufacturing, chemical composition, dimensional tolerances, and testing methods necessary to ensure consistent quality and performance of sintered soft magnetic metals. SIST EN 10331:2003 is harmonized with IEC 60404-8-9 and incorporates related international standards to define measurement and classification protocols.

Key Topics

  • Scope and Application

    • Applies to sintered soft magnetic metals for powder metallurgy components.
    • Excludes castings and semi-finished products.

  • Manufacturing Process

    • Parts are produced by powder metallurgy; manufacturing specifics are often left to supplier discretion.
    • Delivered products generally in a fully annealed state for optimal magnetic properties.

  • Magnetic and Mechanical Properties

    • Defines maximum coercivity and minimum sintered density for various sintered alloys.
    • Typical properties include magnetic polarization, permeability, hardness, and resistivity.
    • Chemical composition data provided as guidance, not for acceptance criteria.

  • Testing and Measurement

    • Magnetic properties - coercivity and polarization - measured mainly on ring-shaped samples per prEN 10281 and EN 10330.
    • Density determined by geometric or immersion methods (EN ISO 2738, ISO 3369).
    • Hardness evaluated by Vickers (EN 24498-1, ISO 4498-2) or Brinell methods (EN ISO 6506-1).
    • Sampling and test scope agreed between purchaser and manufacturer.

  • Classification and Designation

    • Materials categorized by maximum coercivity.
    • Material designations begin with 'S' for sintered, followed by alloy type (Fe, FeP, FeSi, FeNi, FeCo) and coercivity code.

  • Ordering Information

    • Requires clear specification of material designation, dimensions, quantities, test scope, and any special requirements.

Applications

SIST EN 10331:2003 materials are integral in producing components requiring optimized soft magnetic properties such as:

  • Magnetic cores for electrical machines and transformers.
  • Inductors and magnetic sensors.
  • Electromagnetic actuators and relays.
  • Components in power electronics where low coercivity and high permeability are critical.
  • Specialized parts requiring precise magnetic performance combined with mechanical integrity.

The standard supports manufacturers and purchasers in specifying sintered soft magnetic metals for reliable application performance and consistency.
