1 Grey 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.
1 Grey can be used in a powder blower or shaken from a bottle during magnetisation, 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.
- Sharp, colour-contrast indications on high reflective surfaces
- Good particle buildup for quick detection
- Highly refined for optimal particle shape and sise combination
- Minimal dust build-up
- Does not require a black light or darkened inspection area
