Scrap Metal Sorting with XRF
Practical grade-sorting logic for mixed scrap loads — Ni, Zn, and Cu-Zn fingerprints.
Why XRF in the yard
Visual sorting misses grade families that look identical. One 316 heat sold as 304 can erase margin.
Sorting logic
| Family | Key XRF signal | Action |
|---|---|---|
| -------- | ---------------- | -------- |
| Stainless | Ni < 1% | Ferritic pile (430) |
| Stainless | Ni ~8–10%, no Mo | 304/321 pile |
| Stainless | Mo > 1.5% | 316 pile |
| Aluminum | Zn > 4% | 7075 / high-Zn pile |
| Brass | Pb > 2% | C360 pile |
