Commercial iron is classified based on its varying carbon content, which directly dictates its physi — Metallurgy and Isolation of Elements Chemistry Question

💡 Solution & Explanation

Pig iron, obtained directly from the blast furnace, has the highest carbon content ($\approx 4\%$). Cast iron is made by melting pig iron with scrap iron/coke and has slightly less carbon ($\approx 2-4\%$). Wrought iron (or malleable iron) is the purest commercial form of iron, containing the lowest carbon percentage ($< 0.5\%$).
