Correct Answer: Wrought iron


Solution : The correct option is Wrought iron .

Its carbon percentage is 0.12 - 0.25%. Impurities (Mn, Si, P) are present in low amounts. On melting of cast iron with scrap iron in a reverberatory furnace, wrought iron is formed. It is relatively soft, malleable and fatigue-resistant. The mechanical properties and corrosion resistance are also good in wrought iron.
