Description

Sabour and four co-authors turn copper machining waste into a useful alloy, in a 2026 study. Machining leaves piles of copper chips that are often sold as low-value scrap. The team coated the chips with a thin iron layer using a vapor process, pressed them cold, and fused them with spark plasma sintering. The machining itself had already crushed the copper's inner structure into very fine grains.

During heating, breaks in the iron coat and surface oxides let the metals bond and mix directly. The result was a copper-rich alloy with a small iron addition, fine grains, and scattered iron and oxide particles. The work shows a path for upgrading factory waste into engineering material instead of downcycling it.
