Commercial iron is classified by its carbon content, which heavily influences its mechanical propert — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Pig iron, tapped directly from the blast furnace, has the highest carbon content ($\approx 4\%$). Cast iron, made by remelting pig iron with scrap and coke, has slightly less ($\approx 3\%$). Wrought iron is the purest commercial form, containing the lowest carbon content ($< 0.5\%$).
