It is a recommended in the
scrap metal industry that identifying and pre-sorting your alloys accurately (down to the specific grade / quality, measuring impurities and spec compliance, etc.) can gives you a competitive advantage because then you can really charge what the metals are worth. Otherwise you nearly always end up undercharging for what you have, that's the logic. Admittedly, extra fine alloy testing is extra work, but modern technologies (most notably X-ray fluorescence and optical emission spectrometry make it a no brainer, letting you be your own metal-testing lab. That's the 21st-century way to do scrap metal!
(While we are at it, a question for you all: how many of you do detailed alloy grade pre-sorting? Do you find it useful? How much? And if not, why not? Please share! Thank you in advance.)
