Wrought iron is a low-carbon iron alloy, worked while hot and hammered or rolled to squeeze out most of its slag, leaving a fibrous, layered internal structure. Tougher and more ductile than the more brittle cast iron, and easily forge-welded, it was the principal structural and blacksmithing iron from antiquity through the nineteenth century, before the Bessemer and open-hearth processes made mild steel cheaper and displaced it almost entirely.

Facts
Disputed
Origin Year
1200 BCE 1
Bloomery-smelted wrought iron is attested in the Near East and Anatolia from around the twelfth century BCE, marking the start of the Iron Age in the region.
Primary Use
Ornamental ironwork, chains and ships anchors, and, in the nineteenth century, structural beams and boiler plate, valued for toughness, ductility and ease of forge welding, before steel displaced it. 1

Cast Iron, Materials

Wrought iron and cast iron are the two pre-steel iron materials, distinguished chiefly by carbon content and resulting brittleness.

Forging, Methods

Wrought iron is worked and consolidated principally by forging and hammering, not casting.

The Wheel, Inventions

Celtic chariots added an iron rim around the wheel in the first millennium BCE, roughly two and a half millennia after the earliest wooden wheels.
