MPI is a widely used Non-Destructive Testing method which can locate surface or subsurface (up to 2-3 cm below surface) defects in ferromagnetic materials.

A magnetic field is applied to the material. The surface is then coloured in white contrast paint and a black ink wet suspension of ferrous iron particles is applied. Discontinuities in the surface area vertically cut the magnetic field and cause magnetic flux to leak, which attracts the iron particles and reveals the indications.

We use a complete range of equipment and consumables to guarantee speed, economy and excellent testing quality.
