By cultivating spherical graphite macromolecules and adding them into the cast iron material, the resulting composite material has performance far superior to that of conventional cast iron, making the structural performance of this ductile iron comparable to that of steel structures. At the same time, because ductile iron structures can be manufactured through casting and demolding, the production and subsequent processing costs are greatly reduced. Therefore, ductile iron workpieces can be used as a substitute for steel structures when the strength requirements of the structural parts are relatively low.
