Description
An alloy of iron with carbon that is hard, brittle and nonmalleable. Cast iron contains about 2 to 4% carbon and 1 to 3% silicon. It was made in China by at least the 3rd century BCE. The technique for its production did not reach Europe until medieval times. Cast iron is manufactured by melting scrap iron or pig iron in a cupola that is in contact with the coal fuel, then casting the molten iron into a mold. It is inexpensive and easy to make. In the 1830s, cast iron was used for structural and decorative building components in North America. It was also used for cast iron pipe, stove pipe, firebacks, cauldrons, and cannons.
See also gray cast iron, and white cast iron.
Synonyms and Related Terms
grey cast iron; gray cast iron; Gusseisen (Deut.); fonte (Fr.); gietijzer (Ned.); gjutjärn (Sven.); hierro fundido (Esp.); ferro fundido (Port.)
Other Properties
Gray cast iron (with silicon) has less tesiile strength and shock resistance than steel. It is difficult to weld.
The seasoning or impregnation of cast iron cookware with oil minimizes rusting.
