#1 Gray

Colored Non-fluorescent Magnetic Particles

#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.

Benefits

Sharp, color-contrast indications on high reflective surfaces
Ready-to-use
Good particle buildup for quick detection
Highly refined for optimal particle shape and size combination
Minimal dust build-up
Does not require a black light or darkened inspection area
