Copper, brass, bronze: differences
At first glance, copper and its main alloys—brass and bronze—may look similar due to their shared metallic base. However, these three materials have distinct compositions, shades, and applications.
In the recycling and recovery market, these three copper-based metals do not hold the same value. Knowing how to correctly identify them before selling allows you to avoid sorting errors and secure the best payout price for each category.
1. Copper (Pure Metal)
This is the metal in its purest form, highly conductive and malleable. It is the most sought-after and highest-valued material by recycling specialists.
- Color: Highly characteristic reddish-orange shade when cut or scratched.
- Common uses: Plumbing pipes, electrical wires and cables, motor windings, roofing sheets.
- Indicative value: Estimated buyback between €8.50 and €10.30 / kg (depending on grade: mixed or bare).
2. Brass (Copper and Zinc Alloy)
Brass is an alloy primarily combining copper and zinc. Harder than pure copper, it offers excellent corrosion resistance and easy machinability.
- Color: Bright golden yellow tone (visually resembling gold).
- Common uses: Faucets, plumbing fittings, door handles, locks, musical instruments, shell casings.
- Indicative value: Estimated buyback between €3.50 and €5.70 / kg.
3. Bronze (Copper and Tin Alloy)
Bronze combines copper with tin (sometimes adding other elements like phosphorus). It is a dense material, highly resistant to friction and mechanical wear.
- Color: Darker, matte reddish-brown shade compared to copper.
- Common uses: Statues, boat propellers, bushings/bearings, industrial gears, clockwork parts.
- Indicative value: Estimated buyback between €5.00 and €7.00 / kg.
