Gunmetal bronze scrap is a high-demand tin bronze alloy prized for its excellent castability, corrosion resistance, and consistent metallurgy. Commonly recovered from industrial valves, pumps, bearings, marine fittings, and cast components, gunmetal offers buyers a reliable, high-copper feedstock suitable for foundry remelting and alloy blending.
Through Scrap Trade, buyers can source verified gunmetal bronze scrap across Australia with transparent grading, bulk availability, and compliance-ready transactions—ideal for domestic production or export programs.
What Is Gunmetal Bronze Scrap?
Gunmetal is a traditional tin bronze alloy, typically composed of:
- Copper: ~85–90%
- Tin: ~5–10%
- Zinc: ~2–5% (varies by specification)
This composition delivers strength, wear resistance, and seawater corrosion performance, making gunmetal a preferred alloy for pressure-handling and marine applications.
Common Sources of Gunmetal Scrap
- Industrial and marine valves
- Pump bodies and housings
- Bearings and bushings
- Pipe fittings and flanges
- Foundry returns and casting offcuts
Because these components are cast to specification, gunmetal scrap provides predictable recovery compared to mixed bronze.
Why Buyers Prefer Gunmetal Bronze Scrap
1. High Copper Yield with Tin Stability
Gunmetal’s copper-rich base with controlled tin content supports consistent melt chemistry and reduces alloy correction costs.
2. Foundry-Friendly Castability
The alloy flows well during casting, making it ideal for reproducing complex industrial components.
3. Strong Marine & Industrial Demand
Widely used in saltwater systems, pressure fittings, and heavy-duty machinery, gunmetal remains in steady demand year-round.
4. Export Acceptance
Clean, accurately described gunmetal scrap is export-ready and sought by international foundries.
Gunmetal Bronze Scrap Price Factors
Pricing reflects alloy quality and preparation:
| Factor | Impact on Price |
|---|---|
| Verified gunmetal composition | Very High |
| Cleanliness (steel/rubber removed) | Very High |
| Tin content consistency | High |
| Volume (bulk vs small lots) | High |
| Copper market movement | High |
Separated, clean gunmetal consistently outperforms mixed bronze in per‑kg pricing.
Gunmetal vs Other Bronze Scrap
| Scrap Type | Relative Value | Buyer Preference |
