Rare Earth Magnesium (Nodularizer) – High-Efficiency Spheroidizing Agent for Premium Ductile Iron Production

Rare Earth Magnesium (Nodularizer) is a precision-engineered alloy that combines magnesium and carefully selected rare earth elements (such as cerium, lanthanum, and yttrium) in an optimized balance, typically containing 4–8% magnesium and 1–4% rare earths. It is designed to deliver superior and consistent nodularizing performance, excellent fade resistance, and enhanced graphite refinement, ensuring the reliable production of high-integrity ductile iron with uniform, fine graphite spheroids and improved mechanical properties.

Produced through advanced smelting and controlled solidification processes, this nodularizer offers uniform composition, high reactivity control, low oxidation loss, and stable storage characteristics. It enables clean and efficient magnesium treatment in both flow‑through and sandwich methods, contributing to reduced shrinkage tendency, minimized dross formation, and improved casting yield.

We provide foundries with customizable Mg/RE ratios, multiple alloy forms (ingot, cored wire, granular), and tailored process‑integration support to meet the specific demands of automotive, wind energy, heavy machinery, and pipe‑industry castings. Backed by technical expertise and reliable supply, we are committed to being your strategic partner in achieving superior ductile iron quality, optimized treatment costs, and consistent production performance.
