The modern penny (1982 to date) is made of copper plated zinc (97.5% zinc - 2.5% copper).
Before 1982 they were 99.5% copper - 0.50% zinc/tin.
And we have the one odd year, 1943 cents were zinc-coated steel.

Modern pennies are made of copper plated zinc. I once accidently got rid of the copper coat on a penny because I was trying to use it to create a primitive battery, and the small amount of electricity going through the bum-battery that I made took the copper right off.

Depending on the year they were minted, copper, steel or zinc. There were even a few (Very rare) made of bronze.
Copper was before 1972 (I think, could be 82), after that they are made of zinc coated with copper. In the 1940, copper was needed for the war, so pennies were made from steel.
Hope this helps!
