Ferrosilicon Balls (Nodularizer) – High‑Efficiency Spheroidizing Agent for Premium Ductile Iron Production

Ferrosilicon Balls (Nodularizer) are specially designed compacted alloy additives containing carefully balanced magnesium, rare earths, silicon, and iron. They deliver high and consistent nodularizing efficiency, excellent fade resistance, and minimal dross formation, ensuring the reliable production of high‑quality ductile iron with uniform, fine graphite spheroids.

Manufactured through advanced mixing, high‑density pressing, and precise thermal treatment, these nodularizer balls offer uniform composition, controlled reactivity, low oxidation loss, and excellent storage stability. They enable clean, efficient, and controllable magnesium addition in both flow‑through and sandwich treatment methods, contributing to improved mechanical properties, reduced shrinkage tendency, and enhanced casting yield.

We provide foundries with customizable Mg/RE/Si compositions, multiple size options, and tailored process‑integration support to meet the specific requirements of automotive, wind‑energy, pipe, and heavy‑machinery 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.
