Brass vs Bronze
Brass and Bronze are commonly confused, and 3 measured properties separate them — density most clearly.
Brass vs Bronze
Brass
Copper and zinc — the alloy that machines beautifully, resists seawater badly, and sounds better than either metal alone.
Bronze
Copper alloyed with tin — harder than either constituent, and the first engineered material to define an age.
| Property | Brass | Bronze |
|---|---|---|
| Density | 8.4–8.7 g/cm³ higher | 7.4–8.9 g/cm³ |
| Electrical conductivity | 15.9 MS/m higher | 7.4 MS/m |
| Melting point | 900–940 °C higher | 830–1000 °C |
| Tensile strength Only one of the two has a figure we can stand behind, so there is nothing to compare. | 250–550 MPa | Not known |
Why these get confused
similar colour and both copper alloys; zinc against tin is the difference, and it decides marine suitability
The confusion is a real and documented one, not a resemblance we have invented.
