How Nodularisers Improve Graphite Distribution in Castings

Nodularisers play a pivotal role in refining graphite distribution in ductile iron castings. By introducing elements like magnesium, cerium, and rare earth metals, nodularisers promote the formation of spherical graphite nodules rather than flakes. This results in a more uniform microstructure, enhancing mechanical properties such as tensile strength, ductility, and impact resistance. Improved graphite distribution also reduces casting defects like shrinkage and porosity, ensuring higher quality and durability in the final product. Essential for achieving precision and consistency, nodularisers are a cornerstone of modern foundry practices.
