TB Wood's Ductile Iron

Ductile iron can be twice as strong as gray iron. It has considerable elasticity, impact resistance and high yield strength. The superior mechanical properties of ductile iron can be attributed to its unique graphite shape. The graphite within ductile iron occurs as spheroids, allowing the material to elongate significantly under tensile stress, while still ensuring excellent machining ...
