How does buying and reselling scrap metal (arbitrage) actually work as a business model?
Short answer: The core model is straightforward — buy scrap metal below the price you can realistically resell it for, typically by paying individual sellers or small businesses less than what larger-volume buyers pay, with your margin covering the value you add through aggregation, sorting, transport, and taking on the selling relationship — but the details around consistent sourcing, accurate pricing, and cash flow management are what actually determine whether it's sustainably profitable.

The gap between what an individual small seller can access (limited buyer options, smaller volumes) and what a large-volume buyer pays is where a trader’s margin lives — you’re essentially being paid for the aggregation and relationship work.
Why consistent sourcing matters more than any single deal
A single profitable transaction doesn’t make a business — reliable, repeatable sourcing relationships that keep material flowing in are what make the model sustainable over time.
The cash flow reality
Buying material ties up cash before you’ve resold it, and price movements between purchase and resale can erode margin unexpectedly — managing this timing risk is a core skill in this business model, not an afterthought.
