Every worn end mill, insert and drill bit contains tungsten that is just as valuable as the ore in the ground. As mining quotas tighten and prices swing, that reality is turning scrap carbide into a strategic resource.
The supply arithmetic
The United States has no domestic primary tungsten mining of scale and is effectively reliant on imports and recycling; China alone accounted for roughly 27% of U.S. tungsten imports between 2020 and 2023. New mines or refineries elsewhere typically take three to five years to bring real capacity online. Recycling, by contrast, can respond within a single business cycle.
What gets recovered
- Scrap carbide — worn tooling and rods are reprocessed into tungsten concentrate or APT.
- Grinding swarf and fines — once landfilled, now increasingly collected because price strength made recovery economic.
- Cobalt binder — zinc-processing and electrochemical routes reclaim both tungsten and cobalt.
Quality, not just quantity
The open question is purity. Recycled feedstock must be carefully sorted and refined to match the performance of virgin powder, especially for high-end machining and semiconductor grades. The practical answer for most manufacturers is a blend: recycled material for standard grades, certified virgin powder where performance is critical.
A hedge against volatility
For buyers, a credible recycling programme is a hedge against the kind of 200% swings seen in 2025 and the 55% retracement of 2026. Securing secondary supply smooths cost, reduces import dependence and supports the sustainability claims that customers increasingly demand.
