  • Pig Iron

    Pig iron is an intermediate product obtained during the smelting of iron ore using high-carbon fuel, such as coke, charcoal or anthracite. In addition to iron, pig iron consists of varying amounts of phosphorus, sulfur, manganese, silicon, and carbon. Its high carbon content makes it brittle and, hence, it is used for very limited applications.
