    SINT-D39 Sintered Magnetic Metal Materials for Industrial Machinery

    SINT-D39 Standard for Sintered Magnetic Metal Materials in Industrial Manufacturing


    1. Standard Overview

    DIN 30910-4:2004 is a specialized standard published by the German Institute for Standardization (DIN) that specifies the technical delivery conditions for sintered magnetic metal materials. As Part 4 of the DIN 30910 series on sintered metals, it focuses on powder metallurgy-based magnetic materials, defining their chemical composition, physical properties, magnetic characteristics, mechanical performance, and delivery requirements. It applies to both soft magnetic and hard magnetic (permanent magnet) materials used in industrial manufacturing.

    2. Material Classification & Composition

    (1) Material Types

    Category

    Typical Materials

    Primary Composition

    Key Features

    Soft Magnetic

    Pure Fe, Fe-Si, Fe-Ni

    Fe, Si (1-6%), Ni (30-80%)

    High permeability, low coercivity, low losses

    Hard Magnetic

    AlNiCo, Sintered NdFeB, Ferrites

    Fe, Co, Ni, Al, Nd, B

    High coercivity, high remanence, permanent magnetism

    (2) Key Chemical Requirements

    • Fe-Si (Silicon Steel): 1–6% Si to reduce eddy current losses and increase resistivity.
    • Fe-Ni (Permalloy): 30–80% Ni for extremely high initial permeability (μ > 50,000).
    • Fe-P (Phosphorus Iron): 0.3–0.8% P to enhance corrosion resistance and permeability.
    • Sintered NdFeB: Nd-Fe-B base, possibly with Co or Dy for improved temperature stability.

    Impurity Control: Strict limits on sulfur (S), oxygen (O), etc., to prevent magnetic degradation.
