Ductile cast iron - pamline.com

The term 'cast iron' covers a wide variety of iron, carbon and silica alloys. Discovered in the 1940s, ductile cast iron is produced thanks to the addition of a small amount of magnesium to molten grey cast iron. This process gives it exceptional properties in terms of mechanical resistance and bending.
