In the world of metallurgy and industrial manufacturing, Ferro Silicon (Fe Si) stands as one of the most essential and versatile ferro alloys. At Beifang Alloy, we take pride in producing high-quality Ferro Silicon that meets the demands of various industries, ensuring efficiency, durability, and performance in every application.

What is Ferro Silicon (Fe Si)?

Ferro Silicon is an alloy of iron and silicon, typically containing 15% to 90% silicon. It is produced by reducing silica (SiO₂) in the presence of iron sources, such as scrap iron or iron ore, in a submerged arc furnace. The result is a durable and highly effective alloy that plays a critical role in steelmaking, casting, and other industrial processes.

Key Applications of Ferro Silicon

Ferro Silicon is a cornerstone in many industries due to its unique properties. Here are some of its primary applications:

  1. Steelmaking:
    Fe Si is widely used as a deoxidizer and alloying agent in the production of steel. It helps remove oxygen from molten steel, improving its strength, durability, and corrosion resistance. Additionally, it enhances the magnetic properties of electrical steels.
  2. Cast Iron Production:
    In the foundry industry, Ferro Silicon is used to inoculate cast iron, promoting the formation of graphite and improving the metal’s machinability, strength, and wear resistance.
  3. Manufacturing of Silicon-Based Alloys:
    Fe Si is a key raw material in the production of other silicon-based alloys, such as Ferro Silicon Magnesium (Fe Si Mg), which is essential for ductile iron production.
  4. Chemical and Industrial Applications:
    Ferro Silicon is also used in the manufacturing of silicones, semiconductors, and other silicon-based chemicals. Its high silicon content makes it a valuable material in the electronics and solar energy industries.
