Magnetic particle testing
Reliable detection of near-surface defects
Magnetic particle testing is a non-destructive testing method used to detect cracks and defects in or near the surface of ferromagnetic materials. It is used to identify material- or process-related irregularities at an early stage and to ensure the quality and operational safety of components.
For the inspection, the component is magnetized. If there are cracks or defects in the material, magnetic stray fields are generated at these locations. Magnetic particles applied to the surface accumulate at these stray fields, making the defects visible.
Magnetic particle testing is suitable for both individual parts and mass-produced parts. The existing testing system can inspect components up to900 mm in length. The method is fast, effective, and enables reliable quality control directly within the manufacturing process.

Your Questions, Answered
We have compiled a list of frequently asked questions to help you better understand our services.
What is a magnetic particle inspection?
Magnetic particle testing is a non-destructive testing method used to detect cracks and discontinuities on the surface or just below the surface of ferromagnetic materials.
What materials can be tested?
This process is suitable only for ferromagnetic materials, as the component must be magnetized.
What kinds of errors can be identified?
Magnetic particle testing is particularly effective for reliably detecting surface cracks and near-surface defects. Defects located deep within the material cannot be detected using this method.
How does the exam work?
After the component has been magnetized, magnetic particles are applied. The particles accumulate in areas where the material is irregular, making these areas visible.
For which components is this process suitable?
The test is suitable for both individual and mass-produced parts. Components up to900 mm in length can be tested.
Does the inspection alter the component?
No, magnetic particle testing is a non-destructive method and does not affect the function or material properties of the component being tested.
