Brass, Bronze, and Copper: Know the Difference at the Scrap Yard

Published September 10, 2024

Key Takeaway

These three metals look similar but pay very different prices. Knowing which is which puts more money in your pocket.

Copper, brass, and bronze are all reddish or golden metals that can be hard to tell apart. Here's how to identify each.

Copper

Pure or near-pure copper is distinctly reddish-orange, especially when freshly cut or scraped. It's the most valuable of the three for scrap. Over time, it oxidises to a darker brown or green (patina). Pipes, wire, and sheet are the most common copper scrap.

Brass

Brass is a copper-zinc alloy. It appears more golden-yellow than red. Old plumbing fittings, valves, taps, and cartridge cases are typically brass. Brass is non-magnetic. Red brass (higher copper content) has a more orange-gold tone and pays more than yellow brass.

Bronze

Bronze is a copper-tin alloy, often with traces of other metals. It appears slightly more brown or reddish than brass, with a warmer tone. Old bearings, bushings, ship fittings, and bells are often bronze. At most yards, bronze is bought alongside brass at similar or slightly higher prices.

How to tell them apart

At a glance: copper is red-orange, brass is yellow-gold, bronze is brown-gold. When in doubt, ask a yard grader — they assess these metals daily and can identify them quickly.

Magnet test

None of these metals are magnetic. If a magnet sticks, it's steel, not copper, brass, or bronze.
