What is Ferrosilicon?

Ferrosilicon is a ferroalloy (an alloy of iron and silicon) containing between 15% and 90% silicon. It also contains a high percentage of iron silicides. Its melting point is in the range of 1200°C to 1250°C. Ferrosilicon also contains 1% to 2% of calcium and aluminium. A main use of Ferrosilicon is as deoxidizer to remove oxygen from hot metal in steelmaking.

Ferrosilicon products from this international distributor

DMS Powders supplies the following Ferrosilicon products, namely Milled and Atomised Ferrosilicon:

  • Milled ferrosilicon: Milled Ferrosilicon products are formed by means of a two-fold process that consist of melting and milling processes. The melting process takes place in an induction furnace, where the ferrosilicon and high grade plate steel are combined. Milled Ferrosilicon product will undergo screening and classification after it has cooled.
  • Atomised ferrosilicon: Atomised Ferrosilicon is a ferrosilicon powder product which is produced by melting high purity ferrosilicon with scrap and casting into a high-pressure water jet. The high-pressure water atomisation results in a fine particle distribution, which is then separated and classified according to grade.


Our packaging has been specifically designed for:

  • Ease of handling
  • Safety
  • Product integrity
