Magnetic Particle Inspection

XPERT Solutions for Your Specific Needs

Magnetic Particle Inspection is a non-destructive testing (NDT) service for detecting surface defects that are invisible to the naked eye on relatively smooth and non-porous surfaces. The basis of the testing is the use of surface wetting and capillary action. After application of penetrant and removing any excess, the penetrant that rises to the surface indicates the presence of surface anomalies.

This inspection service covers an extensive range of products and materials, including:

• Metal

• Composites

• Ceramic

• Iron

• Nickel

• Cobalt

Advantages of Magnetic Particle Inspection

• Easy and quick procedure

• High sensitivity to small defects and flaws

• Applicable to most materials

• Immediate visual indication of surface anomalies

• Inspect large parts or areas at low cost

XPERT upholds the highest standards of quality assurance for NDT services.

XPERT Engineering Solution is a reputable company that specialises in the provision of testing, inspection and quality assurance services in Malaysia.


Magnetic particle testing is an NDT method used to detect surface and slightly subsurface flaws in ferromagnetic materials such as iron, nickel, and cobalt.

Only metal substances can be tested using this the magnetic particle NDT method.

The product being tested is magnetised to produce magnetic lines of force in the material. Flaws are detected when these lines of force meet a discontinuity.

Magnetic particle testing is a quick and relatively easy NDT technique widely used in many industry sectors such as aerospace, automotive, petrochemical, structural steel, and power generation. It gives an immediate indication of defects and discontinuities in materials such as iron and steel.
