Short answer: Cast iron is iron-carbon-silicon with 2–4 % carbon, poured into moulds for parts where stiffness, wear resistance, damping and low cost beat high tensile strength. Grey iron’s graphite flakes damp vibration (engine blocks, machine beds); ductile (spheroidal-graphite) iron adds toughness and ductility (pipe, crankshafts, auto); malleable and white irons cover fittings and wear parts. Grade choice balances machinability, strength and shock resistance.
