Magnaflux Dry Method Non-Fluorescent Magnetic Particles

Magnaflux Dry Method Non-Fluorescent Magnetic Particles offer superior surface crack detection for ferrous materials under visible light inspection. The Magnavis® dry powder line includes multiple color options (#1 Gray, #2 Yellow, #8A Red) providing strong contrast on various metal surfaces. These ready-to-use, free-flowing magnetic powders effectively detect surface and slightly subsurface discontinuities during dry method magnetic particle testing (MPT). Ideal for non-destructive testing (NDT) applications, these colored magnetic particles deliver clear, sharp indications across diverse backgrounds. The complete product line ensures reliable flaw detection and quality control in industrial magnetic particle inspection processes.

Dry Method Non-Fluorescent Magnetic Particles - Uses and Applications

Primary Purpose:

Dry method magnetic particle testing to provide strong contrast on metal surfaces for detecting discontinuities

Specific Applications:

  • Surface Inspection: Detecting surface and near-surface discontinuities in ferromagnetic materials
  • High Contrast Detection: Providing strong contrast on most metal surfaces, including high reflective surfaces during dry method mag particle testing
  • Versatile Surface Coverage: The particles come in different colors (white-gray, yellow, red) to optimize contrast against different colored metal surfaces

Key Characteristics:

  • Dry Application: Applied as a powder without liquid carrier, making them suitable for situations where wet methods aren't practical
  • Visible Light Inspection: Unlike fluorescent particles, these are viewed under normal white light rather than UV light
  • Non-Fluorescent: They rely on color contrast rather than fluorescence for defect indication

Industrial Uses:

These particles are commonly used in non-destructive testing (NDT) applications across various industries including aerospace, automotive, manufacturing, and maintenance operations where magnetic particle inspection is required to detect cracks, inclusions, seams, and other material discontinuities in ferromagnetic parts and components.

The dry method is particularly useful in field applications, on large parts that can't be easily immersed in wet particle baths, or in situations where contamination from liquid carriers must be avoided.

Magnaflux offers the following Dry Method Non-Fluorescent Magnetic Particles under their Magnavis® product line:

#1 Gray

  • Pale white-gray particles provide strong contrast on most metal surfaces, including high reflective surfaces during dry method mag particle testing
  • Ideal for castings, dark surfaces, detecting medium, large and coarse discontinuities, extreme temperatures, field testing, forgings, in-service inspections, large parts, light, medium, dark surfaces, rough/textured surfaces, spot inspections, weld testing

#2 Yellow

  • Pale yellow particles provide strong contrast on light, medium and dark colored metal surfaces during dry magnetic particle testing
  • Part of the Magnavis® product line for general purpose applications

#8A Red

  • Red particles provide strong contrast on most metal surfaces during dry magnetic particle testing

Key Features of Magnaflux Magnavis® Dry Method Particles:

  • Ready to use, free flowing, general purpose magnetic powders designed to produce superior indications of surface and slightly subsurface discontinuities in ferrous materials
  • Ready-to-use for visible light flaw detection of surface and slightly subsurface discontinuities in ferrous metals
  • Can be applied using powder blowers or shaken from bottles
  • Detect defects including fatigue cracks, grinding cracks, inclusions, laps, quenching cracks, seams, shrink cracks, tears, and welding defects

These three colors (#1 Gray, #2 Yellow, #8A Red) provide optimal contrast against different surface colors and conditions to ensure maximum defect visibility during magnetic particle inspection.
