They're made of copper (before 1982) or copper-plated zinc (after 1982). Both are non-ferrous metals and so they don't rust.
However, in 1943 the Mint made cents out of steel because copper was needed for the war effort. These cents did rust, which is why it's hard to find them in decent condition today.

Do pennies rust faster in saltwater or in fresh water?
Pennies are made of copper and don't rust unless they are the zinc pennies issued in 1942 and 1943. However, zinc will not rust either. The so-called steel pennies minted during World War II were made of steel and coated with zinc. If the penny becomes damaged or if the zinc coating is compromised, the underlying steel will rust if exposed to the proper elements. Pennies do corrode though.
