Product Data Sheet – MAGNAGLO MG 601
Wet Method Fluorescent Magnetic Particles
MAGNAGLO® MG 601 is a powder concentrate used to prepare fluorescent inks for high-sensitivity, wet method magnetic particle testing. The ink gives clear bright yellow/green indications when viewed in a darkened area under UV(A) of peak wavelength 365 nm.
MG 601 is a top-up for MAGNAGLO® WB-655 ink concentrate.
Increases indication detection
- Find smaller, finer indications in critical applications with these highly sensitive particles.
Minimises inspection time
- Clear, bright indications form quickly with minimal background fluorescence.
Improve inspection consistency and reliability
- Maintain magnetic particle system performance over longer periods of time thanks to the highly-durable, easily-dispersed particles.
- High sensitivity
- Excellent fluorescent contrast
- Excellent particle mobility
- Optimised particle size distribution
- Durable particles
- Easily dispersed
Defect location: surface and slightly subsurface
- Detecting very fine to fine discontinuities
- Critical applications
- Machined parts
- Smooth surface finish
- After secondary processing
- In-service inspections

Instructions for Use
MG 601 is used for bath replenishment and concentration control of MAGNAGLO® WB-655.
During use, the magnetic content of any ink will become depleted so you will need to check your bath strength at least once each day. The most widely-used way of checking an ink’s settlement volume is by using a graduated ASTM pear-shaped centrifuge tube.
When the settlement volume approaches the lower limit, you can add more MG 601 powder to the bath as long as it is still clean and uncontaminated. If the bath appears contaminated, or if it has been in use for a long time, replace the contents.
After inspection, remember to completely de-magnetise your components before cleaning, to ensure easy removal of any residual powder particles.
