Rare Earth Silicon (RE-Si) – Advanced Nodularizer and Multi‑Functional Alloy for High‑Performance Cast Iron

Rare Earth Silicon is a composite alloy that combines carefully selected rare‑earth elements (such as cerium, lanthanum, and yttrium) with silicon in precise ratios, typically containing 25‑40% rare earths and 35‑55% silicon. It serves as a high‑efficiency nodularizer for ductile iron production and a versatile purification & modification agent for specialty steels and alloys.

The alloy delivers superior graphite nodularization capability, strong desulfurization and deoxidation effects, and remarkable inclusion morphology control. It promotes the formation of fine, spherical graphite in cast iron, significantly enhancing tensile strength, elongation, impact toughness, and fatigue resistance. In steelmaking, it effectively modifies harmful inclusions, improves castability, and increases overall metallurgical yield.

Produced through advanced smelting and granulation technology, our Rare Earth Silicon offers consistent composition, low oxidation loss, and excellent dissolution behavior. It is particularly suited for the production of automotive components, wind‑cast parts, heavy‑duty machinery, and high‑grade ductile iron, where demanding mechanical properties and reliability are required.

We provide foundries and steel mills with customizable RE‑Si ratios, multiple particle‑size options, and tailored addition‑process guidance, backed by expert technical support. We are committed to being your strategic partner in elevating material performance, reducing production costs, and achieving superior quality in high‑value castings and steels.
