Bronze is a combination of copper and tin; brass is a combination of copper and zinc, which is why the colors look different - bronze is redder and brass is yellower when new. Tin is much more expensive than zinc (being rarer) and is much less prone to pitting - thus bronze tends to have a smoother finish than brass. I've had furniture parts that I designed cast in both bronze and brass, and the bronze was much easier to plate. Left unfinished, they can both turn greenish when patinated, but bronze can also turn black. Bronze statue of Perseus in Piazza Della Signoria, Florence

Replacing the old trestle bridge on the left that crosses over the river in my community. The new bridge is temporary! Not sure what happens next.
