The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel.

Why is wrought iron so expensive?

Why is Wrought Iron So Expensive? Wrought iron is made by repeatedly heating and reworking cast iron. This manufacturing process that gives wrought iron its laminar structure makes it a costly material. It has a far higher tensile strength and is more ductile than cast iron.
