Scrap Metal Sorting
Fast-sort workflows for mixed loads — Ni for stainless, Zn for Al, Cu-Zn for brass.
Intermediate20 min
Yard workflow
1. Visual pre-sort — magnetic vs non-magnetic piles
2. XRF spot test — Ni reading splits 304/316 from 430
3. Aluminum — Zn fingerprint for 7075 vs 6061
4. Brass — Cu-Zn ratio, Pb for C360 vs H62
5. Document — photo + grade label for downstream buyers
ROI
One mis-sorted heat of stainless can cost thousands. Portable XRF pays back in weeks at active yards.
