The product is Ferro Silicon Magnesium ( Nodulizer ) supplied by Henan Guorui Metallurgical Co., Ltd., a Chinese alloy producer. It contains magnesium in the range of 25‑30 % and silicon between 38‑44 % as stated in the supplier data. These alloying elements are combined with iron, calcium and aluminium to form a nodulizing additive for ductile iron casting. The composition is designed to promote graphitisation while controlling excess carbon in the melt.
In the foundry industry, a magnesium content of 25‑30 % is considered high and provides strong deoxidising power. Typical ferro silicon magnesium grades worldwide contain 0.2‑1.5 % magnesium and 40‑55 % silicon, so this product sits at the upper end of the magnesium interval. Calcium and aluminium are usually kept below 0.5 % to avoid brittleness, aligning with standard practice for nodulizers.
The alloy is used in cast‑iron foundries to improve tensile strength and elongation of ductile iron components. Primary buyers include automotive and machinery manufacturers who require reliable castings. Trade terms such as FOB or CIF can be arranged and the supplier indicates flexible minimum order quantities, which should be confirmed directly. Potential importers are advised to request the mill test certificate and verify the certification claims before finalising the purchase.

Before placing an order, importers should obtain the mill test certificate that details the exact chemical composition, including magnesium and silicon percentages. Request the supplier’s ISO and SGS certificates and verify that they are current. Cross‑check the company’s registration details and, if possible, seek references from other buyers who have sourced the same nodulizer.
Discuss the preferred Incoterm, whether FOB from the port of Tianjin or CIF to the destination port, and confirm the estimated lead time for production and dispatch. Because the supplier’s response rate is listed as zero, negotiate clear payment terms such as T/T against documents or a letter of credit before shipment. Ensure that freight forwarders are aware of the powder form to arrange appropriate handling.
Arrange a third‑party inspection at the supplier’s facility to verify the alloy’s grade and packaging integrity. Sampling for laboratory analysis can confirm the magnesium and silicon ranges match the certificate. Request accompanying documentation, such as a certificate of analysis and safety data sheet, to satisfy customs and quality‑control procedures.
