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.

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.
Do pennies rust in water vinegar and bleach?
A mixture of water, vinegar, and bleach is corrosive to most metals. If pennies are placed in it, the copper will oxidize. Rusting is a term only applying to the oxidization of iron, not other metals. The pennies will look a lot cleaner and the liquid will turn blue. If you leave the pennies in the mixture too long, holes may start to form in them.

Do all pennies rust?
No, pennies do not rust in the traditional sense because they are primarily made of copper and zinc, which do not rust like iron. However, they can tarnish or corrode over time due to exposure to moisture and air, leading to a greenish patina known as copper carbonate. The extent of this corrosion can vary depending on environmental conditions.
