Magnetic Particles Suspended in Liquids

  • 7C Black

    7C Black

    Wet Method Colored Nonfluorescent Magnetic Particles

    7C Black is a highly-sensitive magnetic particle powder for nonfluorescent (visible) wet method magnetic particle testing. Particle suspensions prepared with 7C Black provide clear, strong indications and are ideal for locating fine and medium discontinuities on finished parts.

  • 7HF

    7HF

    Oil-Based Visible Magnetic Particle Suspension

    A highly-sensitive oil-based magnetic particle aerosol for nonfluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts.

    7HF provides clear, strong indications due to the heavy buildup of the highly magnetic particles.

  • AX-52

    AX-52

    Water-Soluble Corrosion Inhibitor

    AX-52 is a water-soluble corrosion inhibitor developed specifically for water-based magnetic particle suspensions. It provides excellent corrosion inhibition to protect parts and equipment from rusting.

    When using water as a magnetic particle vehicle, metal parts can be protected from corrosion by using AX-52, which comes as a clear to amber liquid. AX-52 dissolves quickly in water, and can be used in all wet method water baths to improve the corrosion protection.

  • MV-740

    MV-740

    Water-Based Visible Magnetic Particle Suspension

    A highly-sensitive water-based magnetic particle fluid for non-fluorescent (visible) wet method magnetic particle testing to locate fine and medium discontinuities on finished parts. MV-740 provides clear, strong indications due to the heavy buildup of the highly magnetic particles. The product is ready-to-use, so no dilution is required.

    MV-740 is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity.

  • WA-2B

    WA-2B

    Water Conditioner

    WA-2B is a general-purpose water-conditioning powder to enhance surface wetting and magnetic particle dispersion stability in water-based magnetic particle suspensions. Its unique blend of wetting agents, corrosion inhibitors and anti-forming agents eliminates the need for additional water conditioning agents.

    A white granular powder that is added to water baths in wet method magnetic particle testing with no further bath treatment required. WA-2B features good surface wetting and particle dispersion, and will not cake in storage. WA-2B is added to the water bath and stirred until dissolved before the magnetic particles are added.
