Magnetic Particle

Magnetic Particle

Magnetic particle is an inspection method for detecting defects in ferrous materials.  This inspection method is applied to raw materials (billets or slabs), material in the early stages of manufacturing (forgings, castings), or machined parts before they are put into service.  It is also used for inspecting structural parts (e.g., landing gear) that have been in-service for some time to find fatigue cracks.
