Short answer: Both are copper alloys, but brass is mainly copper plus zinc (golden, easy to machine, great for fittings and decor), while bronze is copper plus tin (or aluminum/silicon), darker, harder, and superior for bearings, marine, and wear parts. Choose brass for machinability and looks; choose bronze for strength, wear, and seawater service.
At a Glance
Composition and Color
Messing is copper with zinc (often 10-40%); some grades add lead for machining or manganese for strength. It is golden-yellow and takes a bright finish. Brons is historically copper with tin, though modern ‘bronzes’ use aluminum, silicon, or manganese instead of tin. It is reddish-brown to dark brown.
Strength, Wear, and Corrosion
The chart shows bronze generally wins on hardness, wear resistance, and fatigue – ideal for bearings and bushings. Brass wins on machinability and formability, and both resist corrosion well, though bronze (especially silicon/aluminum bronze) is the better choice in seawater.
Typische toepassingen
- Brass: valves, fittings, musical instruments, decorative trim, ammunition, electrical connectors.
- Bronze: bearings, bushings, marine hardware, sculptures, springs, and coins.

Veelgestelde vragen
Brass is copper-zinc (golden, machinable); bronze is copper-tin or copper-aluminum/silicon (darker, harder, wear-resistant).
Bronze is generally stronger and harder with better wear and fatigue resistance; brass is softer and easier to machine.
Bronze – particularly silicon and aluminum bronzes – resists seawater far better than most brasses, which can suffer dezincification.
Bronze is usually the pricier of the two because of tin and alloying complexity, though prices track copper and alloying metals.
Brass: fittings, instruments, decor, connectors. Bronze: bearings, bushings, marine hardware, sculptures.
