Standards for Positive Material Identification

Positive material identification or PMI is the verification of metal alloys based on their chemical composition.  This methodology is used for a wide range of applications where the grade of metal alloy used in a particular application needs to be confirmed.  PMI is used in a wide range of applications, but most commonly in industrial settings where using the wrong metal alloy grade can result in premature corrosion or even failure creating a potentially serious safety hazard.  The chemical verification of alloys already being used in industrial applications often requires that the analysis be non -destructive and performed insitu. nickel 718.jpg

We offer a wide range of metal alloy reference materials for PMI applications which are available as 38mm diameter discs in varying thicknesses appropriate for handheld XRF  or OES instruments.  We have over 350 different materials covering everything from the most common steel grades to more exotic Nickel and Titanium alloys. 

Our portfolio of reference materials includes:

  • Stainless steels
  • Low alloy and Carbon Steels
  • Tool Steels
  • Nickel and Cobalt Alloys
  • Titanium alloys
  • Copper Brass and Bronze
  • Aluminum Alloys

These PMI standards of “XRF Coins” are available as individual pieces or in larger sets. We also offer a Master Alloy 100 set for the most demanding applications
