ductile iron, ductile cast iron, spheroidal graphite cast iron, spheroidal graphite iron, spheroidal cast iron, SG iron, SG-iron, spherulitic-graphite cast iron, spherulitic graphite cast iron, high-duty cast iron, nodular graphite cast iron, nodular cast iron, nodular graphite iron, nodular iron
malm, mis on töödeldud sulaolekus magneesiumi ja tseeriumiga, mille tulemusena saadakse sferoidaalse või mügara kujuga grafiit; tuntud ka sitke malmina, kuna omab mõõdetaval määral ka sitkust (vt keragrafiit, mügargrafiit, grafiitmalm; vrd liblegrafiitmalm, kompaktgrafiitmalm, tempermalm), a cast iron that has been treated while molten with an element such as magnesium or cerium to induce the formation of free graphite as nodules or spherulites, which imparts a measurable degree of ductility (see: spheroidal graphite, nodular graphite, graphitic cast iron; compare: flake graphite cast iron, compacted graphite cast iron, malleable cast iron)
