Ferro Silicon Specifications

Ferrosilicon is an alloy of iron and silicon, commonly used as a deoxidizer, alloying agent, and refining agent in steelmaking. The grades of ferrosilicon are classified based on their silicon content, which varies from 15% up to 90%.

Two commonly used grades of ferrosilicon are ferrosilicon 72 and ferrosilicon 75, which refer to the silicon content of the alloy. Ferrosilicon 72 contains approximately 72% silicon,  and small amounts of carbon, sulfur, and other impurities. Ferrosilicon 75 contains approximately 75% silicon,  and similar impurities.

The specifications of these grades of ferrosilicon may vary depending on the manufacturer, but the following are some typical characteristics:

- Ferrosilicon 72:
- Silicon content: 72% min
- Carbon content: 0.2% max
- Sulfur content: 0.02% max
- Phosphorus content: 0.04% max
- Size range: 10-50mm, 50-100mm, 100-200mm, or customized
- Packing: In 1MT big bags or as per customer's requirement

- Ferrosilicon 75:
- Silicon content: 75% min
- Carbon content: 0.2% max
- Sulfur content: 0.02% max
- Phosphorus content: 0.04% max
- Size range: 10-50mm, 50-100mm, 100-200mm, or customized
- Packing: In 1MT big bags or as per customer's requirement

Other factors that may affect the specification of ferrosilicon include density, melting point, and the presence of other elements or impurities. Before purchasing ferrosilicon, customers should consult with the manufacturer or supplier to ensure that the specifications meet their requirements.
