Product Description

Ferrosilicon magnesium (Fe-Si-Mg alloy) is a ferroalloy composed mainly of iron (Fe), silicon (Si), and magnesium (Mg), with trace elements like calcium (Ca) and rare earths (RE) sometimes added. It is primarily used as a nodulizer in ductile iron production, transforming flake graphite in cast iron into spherical (nodular) graphite, thereby significantly improving mechanical properties (toughness, strength) of castings.

• Core Nodulizing Ability: Magnesium (Mg) is the key element, capable of transforming flake graphite in cast iron into spherical form, ensuring high nodularity.
• Purification Effect: Silicon (Si) assists in deoxidation, while magnesium and calcium (Ca) effectively desulfurize (sulfur <0.02%), preventing nodulization failure.
• Controllable Reactivity: Balanced magnesium content reduces gas evolution (to prevent porosity) while ensuring sufficient nodulizing effect.
• Stable Composition Strong Adaptability: Low impurities (e.g., P≤0.05%)

Applications

• Ductile Iron Casting (Core Application):
• Automotive Industry: Produces crankshafts, camshafts, and differential cases (requires high toughness and fatigue resistance).
• Engineering Machinery: Manufactures hydraulic cylinder blocks, excavator arms, and gearboxes (withstands heavy loads and impact).
• Pipe Fittings: Used for high-pressure water/gas pipes (needs pressure resistance and ductility).
• Other Cast Irons: Improves structure of malleable cast iron, reducing brittleness in thick-walled castings.
