 INTRODUCTION
 

## What is Ferrosilicon?

 

 
 **[Ferrosilicon (FeSi)](https://ferrosilicon.co/ferrosilicon-fesi/)** is an iron-silicon alloy containing **15–90% silicon**, with the most common commercial grades being **FeSi65**, **FeSi70**, and **FeSi75**.
 This ferro alloy plays a critical role in modern steelmaking as both a powerful **deoxidizer** and an **alloying element**, improving steel quality, mechanical strength, and production efficiency.
