Ferro Silicon Aluminum (FeSiAl)
Good Deoxidation Ferro Silicon Aluminum – Efficient FeSiAl for Clean Steel Production
Ferro Silicon Aluminum (FeSiAl) is a composite ferroalloy widely used as a high-efficiency deoxidizer in steelmaking and foundry industries. By combining the advantages of silicon and aluminum, FeSiAl delivers excellent deoxidation performance, improves molten steel cleanliness, and reduces non-metallic inclusions.
Thanks to its stable chemical behavior and high recovery rate, ferro silicon aluminum is increasingly preferred over single-element deoxidizers. ZhenAn supplies good deoxidation ferro silicon aluminum with consistent composition and controlled impurities for industrial and B2B procurement.
Chemical Composition of Ferro Silicon Aluminum
| Element | Typical Content |
|---|---|
| Silicon (Si) | 45% – 60% |
| Aluminum (Al) | 8% – 15% |
| Iron (Fe) | Balance |
| Carbon (C) | ≤ 0.5% |
| Phosphorus (P) | ≤ 0.05% |
| Sulfur (S) | ≤ 0.03% |
| Appearance | Gray metallic lumps or granules |
All FeSiAl products are supplied with strict quality control, and Mill Test Certificates (MTC) are available upon request.
Why Ferro Silicon Aluminum Offers Good Deoxidation
Strong Deoxidation Ability
Both silicon and aluminum have strong affinity with oxygen. When used together, FeSiAl provides rapid and deep deoxidation, effectively reducing dissolved oxygen in molten steel.
Improved Inclusion Control
The combined deoxidation reaction forms low-melting-point oxides, which are easier to float up and be removed, resulting in cleaner steel.
High Alloy Recovery Rate
Compared with pure aluminum or silicon addition, ferro silicon aluminum shows higher recovery efficiency, minimizing alloy loss and improving cost control.
Stable Metallurgical Performance
FeSiAl reacts smoothly in molten steel, reducing violent reactions and improving operational safety during refining.
Applications of Ferro Silicon Aluminum
Carbon Steel and Alloy Steel
FeSiAl is widely used as a primary or auxiliary deoxidizer in carbon steel and low-alloy steel production, improving mechanical properties and surface quality.
Foundry & Casting Industry
In cast iron and steel casting, ferro silicon aluminum helps reduce gas porosity and inclusion defects, enhancing casting integrity.
Secondary Refining Processes
During LF, VD, and other refining processes, FeSiAl contributes to final deoxidation and steel cleanliness control.
Special Steel Grades
FeSiAl is suitable for steels requiring low oxygen content and stable composition, such as structural steel, engineering steel, and pipeline steel.
