Is it reasonable to request an XRF or spectrometer reading before agreeing to a price on alloy scrap?
Short answer: Yes, this is standard, reasonable practice for any meaningful volume of alloy scrap — an XRF reading takes seconds and gives an actual elemental composition breakdown, and a seller trading in real volume should have no issue providing one or letting you test a sample yourself before you commit to a price based on assumed alloy content.

Alloy composition directly determines value for non-ferrous metals especially, and visual identification alone is genuinely unreliable for distinguishing similar-looking alloys. Requesting objective test data before pricing a load isn’t distrust of the seller specifically, it’s standard due diligence any buyer should apply.
What to actually ask for
Request either a recent XRF reading with the specific elemental percentages shown, not just a grade name, or ask to test a representative sample yourself if you have access to your own equipment. For larger purchases, a third-party lab analysis is worth the cost.
If a seller resists
A seller who’s reluctant to provide any composition data, or who only offers a grade label without backing data, is either inexperienced or trying to avoid scrutiny — either way, it’s worth pricing conservatively or looking elsewhere for a comparable lot.
