Spheroidal graphite iron, also known as ductile iron, is a type of cast iron with superior impact and fatigue resistance thanks to its nodular graphite inclusions. It is widely used in the automotive industry for components that need to be stronger than aluminium but lighter than steel. The leading supplier of spheroidal graphite iron casting for automotive applications in Europe is Georg Fischer Automotive AG. Passionate about a lighter future, the Swiss-based company enables carmakers and commercial vehicle producers to excel in lightweight construction for lower emissions and increased fuel efficiency.
