Magnaflux Magnaglo MG-450A

Fluorescent Magnetic Particle Premix with MG-410 Particles


MG-450A is a borax-free ultra-high fluorescence magnetic particle premix for locating small, medium and gross discontinuities in high-volume applications using wet method magnetic particle testing. Designed to mix with water, MG-450A improves indication visibility with less background fluorescence because of the high-strength, high-fluorescent MG-410 particles. These high performance particles combine with patent-pending water conditioner and corrosion inhibitor package to create a water bath that requires less maintenance, keeps performing longer and protects parts and equipment from rust.

MG-450A is a great option for high-speed, high volume applications on raw products/materials, after secondary processing, on textured/rough surface finishes or on unmachined parts where indication visibility and through-put are important.


Improves Indication Detection

  • Enhances indication visibility for more reliable inspections with less background due to the high magnetic strength and fluorescent brightness of Magnaflux’s MG-410 particles

Decreases Maintenance

  • Less upkeep and fewer change outs due to the durable, rugged design of MG-410 magnetic particles, so the particles resist wear and tear during use

Reduces Product Use

  • Use less product in each mag bath and save money with high-strength, high-fluorescent particles which perform well at low particle concentrations

Advanced Corrosion Protection

  • Decrease scrap and increase equipment lifespan with patented, corrosion protection to keep parts and equipment free from rust

Safe to Use

  • Meet or exceeds current safety requirements by eliminating hazards associated with many similar products
