The fastest way to quote Cast Iron

Cast iron is an iron-carbon alloy with carbon content above 2%. Its excellent castability, machinability, and vibration damping make it a workhorse for machine bases, housings, cylinders, and wear-resistant components. Gray iron is most common; ductile (nodular) iron offers improved tensile strength and ductility.
