Malleable Iron

Malleable iron is the oldest member of the family of nodular irons. Like all nodular irons, malleable iron exhibits good ductility. Incorrectly considered by some to be an "old" or "dead" material, malleable iron still has a legitimate place in the design engineer's toolbar. Malleable is the iron of choice for small castings or castings with thin cross sections (less than .25"). Other nodular irons tend to be difficult to produce in these applications. Malleable iron is also preferred for castings seeing duty in low temperature environments since it retains its ductility better than other nodular irons at low temperatures. Used for small castings requiring good tensile strength and the ability to flex without breaking (ductility).
