SHARE

Spheroidal graphite cast iron is considered to be a particularly strong and ductile material. This is due to the globular structure of the graphite, achieved by a special melting treatment. Thanks to this structure, spherulitic graphite cast iron achieves high strength and ductility properties that are almost comparable to those of cast steel. We process the material into cast iron parts for various industries, ranging from plant and mechanical engineering to automotive engineering and the production of parts for wind turbines. Material standard: DIN EN 1563
