Wrought iron is nearly pure iron mixed with a glasslike material. Unlike cast iron, wrought iron is malleable—that is, it can be hammered into various shapes. Wrought iron also resists corrosion (rust) better than cast iron does.
Wrought iron was once used in making many products now made from steel. Today, steel companies produce only small amounts of wrought iron. Most of it is made into porch railings and other decorative items.
