Only steel contains iron, one of the ingredients required for iron oxide (rust). Copper and bronze form other compounds with atmospheric gasses and/or elements found in rain, but they don't form rust.
Steel because copper and bronze will not rust... It will tarnish but not rust
I think Steel will rust the fastest because I've been doing a science fair project and had to test them out and only steel has rusted with in 4 weeks!
Steel, because it is the only one that contains iron. A material must have iron in it to form rust, because rust is iron oxide.
