Material Science: The Ductility Factor
In the specification of pipeline and municipal infrastructure, mechanical resilience is the primary concern. A frequent technical inquiry from engineers and procurement managers is: what s the difference between ductile iron and cast iron? The distinction lies in the microstructure. Traditional gray cast iron is brittle due to its flake graphite, whereas ductile iron is treated with magnesium to form graphite nodules, granting it flexibility and impact resistance similar to steel.
