Particles for Magnetic-Particle Flaw Detectors

Test metals for faulty seams, welding defects, and fatigue cracks, assuring they will be safe even under high stress. Unlike other flaw detectors that only find surface defects, magnetic particles also reveal imperfections slightly below the surface. Use them with magnetic flaw detectors to magnetize your material; particles are attracted to and move towards imperfections.

These particles help you follow ASTM E1444 or ISO 9934, which outline standard practices and quality controls for magnetic particle testing. Approved for use by the military, these particles meet MIL and NAVSEA testing standards, meaning they’re good to use when performance and safety is critical.

Powder particles let you see test results with the naked eye.

When testing round or hard-to-reach material, it’s easier to apply an even layer of spray particles than powder. In order to see the results, you must use a UV light. When under the light, the fluorescent color stands out, so you spend less time examining each part. Use oil-based spray when corrosion is a concern, but it’s harder to clean up than water-based spray.

Plug-In Magnetic Particle Flaw-Detection Kits

This kit comes with a yoke that creates a magnetic field on the part you’re inspecting—apply the powder on ferrous metal and the defects appear.

Contrast Paint for Magnetic-Particle Flaw Detection

Create a high-contrast background for magnetic particles to make flaws easier to spot during inspections. This opaque white paint reduces glare, so you can see where particles are clustered around imperfections. No need for brushes—it comes in an aerosol can that’s easy to use during field testing and spot inspections. Even when the can is upside down, the 360° sprayer won’t sputter or spatter, so you can coat parts evenly without straining your wrist. To speed up inspections, this paint dries quickly, leaving a clean coat that won’t bubble or flake. It works with both wet and dry magnetic particles.
