Magnaflux #1 Gray Non-fluorescent Magnetic Particles
Item No: 01-1716
Pale white-gray particles provide strong contrast on most metal surfaces, including high reflective surfaces during dry method mag particle testing.
#1 Gray provides strong contrast on most metal surfaces during dry method mag particle testing in visible light. It is ready-to-use for visible light flaw detection of surface and slightly subsurface discontinuities in ferrous metals. It can be used in a powder blower or shaken from a bottle during magnetization, and blown off while current is still being applied. On material with a high magnetic retentivity, indications can still be formed after the current has been turned off.
Applications
Defect location: Surface and slightly subsurface
Ideal for: Light, medium, dark surfaces; Detecting medium, large and course discontinuities; Weld testing; Forgings; Castings; Field testing; Spot inspections; In-service inspections; Large parts; Dark surfaces; Extreme temperatures; Rough/textured surfaces
Defect examples: Inclusions, Seams, Shrink cracks, Tears, Laps, Flakes, Welding defects, Grinding cracks, Quenching cracks, Fatigue cracks
