Ferrosiliziummagnesium

Ferro Silicon Magnesium (FeSiMg) is a nodularizing alloy that converts the graphite in molten iron from flake to spheroidal form. Added to the ladle, its magnesium reacts with dissolved sulfur and oxygen, then the residual Mg nucleates compact graphite nodules, while the rare-earth fraction neutralizes trace subversive elements (Pb, Bi, Sb) and stabilizes nodule count. The result is ductile (nodular) iron with the tensile strength and elongation that grey iron cannot reach. It serves ductile iron production, in-ladle nodularization, and general cast iron modification across automotive, pipe, and machinery casting. Typical treatment additions run roughly 1.0-1.8 wt% of the metal charge, tuned to base sulfur, tapping temperature, and the sandwich or tundish-cover method used. This grade carries Si 44-48%, Mg 5-7%, RE 1-2%, Ca 1-3%, Al ≤1.0%, sized 5-25 mm for controlled dissolution and reduced Mg fade, on a GB/T 4138 nodulizer basis. Each lot ships with COA (EN 10204 3.1) and MTC, with Mg/RE verification and Mg-fade discipline. Multi-regional sourcing supports CIF delivery and Gebze bonded stock for fast replenishment, 20 MT FCL or 5 MT LCL. Send your base-iron analysis and target grade for an RFQ.
