Because the metal was shaped, or wrought, by hammering, it came to be called wrought iron. Tools and weapons brought back to Europe from the East were made of an iron that had been melted and cast into shape. Retaining more carbon, cast iron is harder than wrought iron and will hold a cutting edge.

2023/7/16 Wrought iron is a type of iron that is made by heating iron ore and then hammering it into the desired shape. It is a malleable, ductile metal that can be bent and shaped without breaking. Wrought iron has a low carbon content, typically less than 0.3%, which gives it its flexibility and strength.

Methods of producing low carbon wrought iron directly from the ore are known as direct reduction process. After the development of the blast furnace, the DR processes were nearly abandoned. However after 1980s DR processes find wide acceptance because here the iron ore is reduced at lower temperature using low grade coal.
