X-Ray Fluorescence (XRF)

Metal absorbs and then emits X-Rays. The emission spectrum is analyzed for characteristic (or fluorescent) X-Ray energy of the constituent elements.


  • Quickly distinguish between metal families (stainless, low-alloys, nickel-alloys)
  • Distinguish between metals where distinction is not based on carbon content.
  • Acceptance criterion is not dependent on carbon content.
  • Very portable - analyzer is held in one hand.
  • Can grade or analyze small parts.
  • Can be done on clean, uncoated surfaces with no preparation.


  • Will not evaluate Carbon percentage.
  • Unable to evaluate chemistry lighter than Aluminum
