Cast Iron Metallurgy for Dummies

Cast iron is made by re-melting pig iron, often along with substantial quantities of scrap iron and scrap steel and taking various steps to remove undesirable contaminants such as phosphorus and sulphur. Depending on the application, carbon and silicon content are reduced to the desired levels, which may be anywhere from 2 to 3.5% and 1 to 3% respectively. Other elements are then added to the

Ask a Metallurgist: Wrought Iron vs Cast Iron Metal

Cast iron can refer to a range of iron alloys, but it is most commonly associated with gray iron. Despite having the name iron, it isn’t pure elemental iron (Fe on the periodic table)—it’s actually an alloy containing 2–4 percent carbon, plus small amounts of silicon and manganese. Other impurities, such as sulfur and phosphorus, are also common.
