Silicon Metal 553 is one of the most widely used grades in the aluminum industry. With its optimal chemical composition and cost-effectiveness, it is essential for aluminum alloy production, especially for casting and extrusion applications. As a trusted ferroalloy factory, Beifang Alloy delivers consistent quality and reliable supply to global aluminum producers.
Silicon Metal 553 typically contains:
Si ≥ 98.5%
Fe ≤ 0.5%
Al ≤ 0.5%
Ca ≤ 0.3%
In aluminum alloy production, it serves as a critical element to:
✅ Improve casting performance
✅ Enhance strength, hardness, and corrosion resistance
✅ Refine grain structure for better mechanical properties
✅ Reduce costs compared to higher-purity silicon
When sourcing Silicon Metal 553 for aluminum applications, buyers should consider:
Chemical purity and stability
Grain size (lumps, granules, powder)
Packaging formats (jumbo bags, ton bags, palletized options)
Delivery lead times and international logistics
Technical support and material traceability
Beifang Alloy offers tailored packaging, SGS inspection, and flexible delivery solutions to meet your production schedule.
The demand for Silicon Metal 553 has been growing steadily due to:
The expansion of lightweight aluminum automotive components
The rise of recycled aluminum alloys in sustainability efforts
Global focus on energy-efficient building materials and consumer goods
According to recent industry data, China remains the largest producer and exporter of Silicon Metal 553, with increasing interest from Southeast Asia, the Middle East, and South America.
How to choose the right supplier for Silicon Metal 553:
