The spheroidal graphite iron casting process is a process for cast iron containing nodular particles of graphite and is a substitute for lower quality grey cast iron. Thanks to spheroidal graphite cast iron we supply better quality at better prices – compared to the more common grey iron casting process, which we deliberately refuse to use.

Understanding Cast Irons - Ductile Iron

Ductile iron, also referred to as nodular iron or spheroidal graphite iron, was patented in 1948. After a decade of intensive development work in the 1950s, ductile iron had a phenomenal nine-fold increase in use as an engineering material during the 1960s, and the rapid increase in commercial application continues today.
