Magnetic Particle Inspection (MPI)
At Titan Metallurgy, our Magnetic Particle Inspection (MPI) quickly and efficiently detects surface and near-surface flaws in ferrous materials that are not visible to the unaided eye. This form of nondestructive testing (NDT) is used in a large variety of industries due to its cost-effectiveness and short turnaround time.
Magnetic Particle Inspection Process
Magnetic particle inspection detects flaws in ferromagnetic materials by using an electric charge to induce a magnetic field directly or indirectly into a component. Ferrous iron particles – coated with a pigment that glows when exposed to ultraviolet light – are then applied to the part in a dry or wet suspension. The particles will be attracted to a flaw and build up around the leakage to indicate the location of the flaw. This location can be further evaluated to determine the characteristic and cause of the defect.
Magnetic Particle Inspection works to reveal the following defects:
- Seams
- Laminations
- Quench cracks
- Cooling cracks
- Grinding cracks
- Machine tears
- Blasting, pickling cracks
MPI at Titan Metallurgy
Titan Metallurgy has a team of highly trained and experience degreed metallurgists working in accredited testing facilities and with accredited testing equipment. We follow ASTM E1444, ASTM E3024, and ISO 9712 testing standards. All of this knowledge and experience results in a quick turnaround while maintaining accurate results. Additionally, we offer a 24-48 hour expedited turnaround time.
Because MPI relies on a magnetic field, Titan Metallurgy can perform magnetic particle inspection on the following:
- Nickel
- Iron
- Cobalt
- Steel
- Magnetic stainless steel
- Cast iron
However, aluminum, copper alloys, and non-magnetic stainless steel cannot be tested using the MPI method.

Magnetic Particle Inspection Applied
In a recent request, Titan Metallurgy was asked to perform Magnetic Particle Inspection on a crankshaft for a high-performance engine. Through MPI, Titan was able to locate a fatigue fracture in the core engine component. Without this technology, details like these can be imperceivable to the human eye during a typical inspection. This discovery potentially saved the reputable engine builder hundreds of thousands by identifying a major issue before catastrophic failure.
