Product Introduction
Silicon Magnesium (Si-Mg) is a high-performance alloy that combines silicon (Si) and magnesium (Mg) to enhance the properties of metals, particularly in ductile iron production. This alloy is widely used as a nodularizing agent, transforming graphite flakes into spheroidal graphite (SG), which significantly improves strength, ductility, and impact resistance in cast iron.
🔥 Key Components:
- Silicon (40-60%) – Enhances fluidity & castability
- Magnesium (5-30%) – Ensures effective nodularization
- Calcium (0.5-3%) – Improves desulfurization & slag formation control
📦 Available Forms:
✔ Lumps (3-25mm, 10-50mm, or custom sizes)
✔ Powder (50-200 mesh for precise dosing)
✔ Briquettes (Easy handling & reduced oxidation)
Key Features & Benefits✅✨
✅ Exceptional Nodularization – Ensures perfect spheroidal graphite formation in ductile iron, boosting mechanical strength & elongation.
✅ Enhanced Metal Quality – Reduces shrinkage, porosity, and casting defects for superior finished products.
✅ High Reactivity – Low melting point ensures quick dissolution in molten metal, improving efficiency.
✅ Cost-Efficient – Optimizes magnesium usage, reducing waste and operational costs.
✅ Multi-Functional – Acts as a deoxidizer & desulfurizer in steelmaking.
✅ Eco-Friendly – Minimal fume emission & slag formation for cleaner production.
