Pennies were made mostly of copper until  mid-1982, when the composition was changed â¦to 97.5% zinc with a  plating of 2.5% copper.    The only exception was in 1943 when wartime copper shortages forced  the Mint to make pennies out of scrap steel. Bronze cents were  resumed the next year, 1944.
Since it resists corrosion from the air, moisture and seawater, copper has been widely used in coins. Although once made nearly entirely from copper, American pennies are now made from zinc that has been coated with copper. Copper is also used to make water pipes and jewelry, as well as other items. Pure copper is usually too soft for most uses. People first learned about 5,000 years ago that copper can be strengthened if it is mixed with other metals. The two most familiar alloys of copper are bronze and brass.
