Magnetic Particle Inspection

A non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys.

Magnetic Particle Inspection

What is Magnetic Particle Inspection (MPI)?

Magnetic Particle Inspection (MPI) is a non-destructive testing (NDT) method used for the detection of defects, such as cracks, in ferrous materials. It is also known by the trade names MagnaGlow or MagnaFlux.

How Does Magnetic Particle Inspection Work?

This method is performed by creating a magnetic current within steel or iron parts. Fluorescent particles align along surface or shallow subsurface defects and are detected under black light. This service is offered at our Burton Ave location in Waterloo, Iowa.
