Wrought iron is a term that refers to both a type of metal and a process of formation.
Traditionally, wrought iron is a variety of iron. Wrought iron is made with additives that render it twistable with a low corrosion rate. Authentic wrought iron differs from steel in that it is impregnated with tiny slivers of iron silicate known as “slag.” When distributed as fibers, the slivers of iron silicate changes the chemical properties of iron to create a new metal. Wrought iron has tremendous strength under tensile pressure, resistance to corrosion, and malleability.
