Which will not rust? Copper, brass,aluminium - lolitahe69 - 11-25-2021
Copper, brass, and bronze do not rust for the same reason as aluminum. All three have a negligible amount of iron in them. Therefore no iron oxide, or rust, can form. However, copper can form a blue-green patina on its surface when exposed to oxygen over time.
