    Ferrite Magnets

    English English Russian Spanish

    Introduction

    1. Ferrite magnets are ceramic compounds of iron oxides, such as hematite (Fe2O3) or magnetite (Fe3O4), and other metal oxides.
    2. Ceramic magnets are hard and brittle. According to magnetic properties, they can be classified into "soft” ones and "hard” ones. "Soft” magnets have small coercive force, while "hard” ones are featured by large coercive force.
    3. Ferrites produced by us are mainly permanent magnetic ferrite. They are widely utilized in electronic industry, IT industry, automobile industry, etc.
    4. Our ferrite magnets have passed ISO9001, ISO14001, GB/T28001 and SGS.

    Shapes

    1. Charcoal gray magnets are in shapes of discs, rings, blocks, cylinders, arcs, etc.
    2. We also customize ceramic ferrites in various shapes according to customers’ requirements.
    Choose Ceramic Magnet from Following Shapes
    Square Ferrite Magnets
    Disc Ferrite Magnets
    Custom Ferrite Magnets

    Features of Ceramic Magnet

    They are featured by good temperature resistance, low production cost, large magnetic permeability and good magnetic performance. Besides, they are easy to achieve magnetic saturation.
