Many manufacturing processes , the use of alloy verification eliminates a significant amount of scrap and nonproductive labour. Alloy verification can play a very important role in the ISO 9000 or other Quality System certification program.
Portable x-ray fluorescence (pXRF) has long been the main instrument used for alloy identification. These instruments are capable of measuring the chemistry of a sample and then by comparing the measured chemistry to the definition of the various alloy grades determines the grade name.
The latest detector technology has extended the range of alloys which can be measured using these portable instruments.
