Positive Material Identification for the metal alloy industry

Positive Material Identification is a well accepted analytical materials testing and materials identification technique used within the metal alloy industry. It guarantees the materials chemical composition as required for quality control.


On-site Positive Material Identification done by using simple, portable analysers have a number of benefits. For example PMI testing allows the manufacturer:

  • to ensure every part conforms to specification,
  • to identify the correct alloy grade where a critical part is to be replaced,
  • facilitate inward goods inspection to ensure all bought in materials are to specification, etc

Applied correctly, simple Positive Material Identification avoids any potential mix up, costly reworks or out of specification material used incorrectly. PMI testing avoids the failure of a critical component potentially leading, in the worst case, to a catastrophic failure of a process and loss of life.

There are two globally accepted analytical methods for simple on-site Positive Material Identification: X-ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES).

Positive Material Identification and XRF

The X-MET8000 Series is a rugged handheld XRF analyser for PMI testing. It measure in a few seconds – by simply point and shoot -  the key alloying elements in stainless steel and high alloy grades where PMI is most frequently used.

  • Quality control and assurance of micro alloy steels; aluminium and magnesium alloy analysis
  • Trace & light element analysis (Magnesium to Sulfur)
  • Low Chromium analysis, FAC inspection
  • Wires down to 1mm diameter can be identified
  • Inspect pipes, welding seams, and valves for corrosion resistance conformity
