At Beifang Alloy, we take pride in producing and supplying Silicon Metal 553, one of the most widely used silicon grades in the metallurgy and aluminum industries. This guide will help you understand its chemical composition, how to procure it, and what to consider when selecting a supplier.
Silicon Metal 553 is named after its standardized impurity levels:
| Element | Typical Content (%) |
|---|---|
| Silicon (Si) | ≥98.5% |
| Iron (Fe) | ≤0.5% |
| Aluminum (Al) | ≤0.5% |
| Calcium (Ca) | ≤0.3% |
This composition ensures high silicon purity with minimal metallic impurities, making it ideal for:
Aluminum alloy manufacturing
Chemical-grade silicon production
Metallurgical deoxidation
The demand for Silicon Metal 553 is expanding globally, driven by:
Rapid growth in aluminum alloy production
Increased solar-grade polysilicon demand
Strong consumption by automotive and construction industries
Recent market reports forecast stable pricing and steady demand in Asia-Pacific, Europe, and North America.
When sourcing Silicon Metal 553, buyers typically require:
Consistent chemical composition
