- Ferroalloys are among the necessary materials for the metallurgical industry, whose most important application is related to the oxidation and refining of ferrous and non-ferrous metals. These materials are based on iron alloy, along with other additives such as manganese, potassium, molybdenum, silicon, etc., and their production is done in special units. In other words, ferroalloys are different alloys of iron that, in addition to iron, contain a significant amount of one or more elements such as manganese, carbon or silicon.
- It should be noted that ferroalloys are responsible for providing unique qualities in steel and cast iron and play an important role in iron and steel production cycles. Keep in mind that ferroalloys are not limited in properties and are available in different types such as ferromanganese, ferrochrome and ferrosilis etc. Basic and common ferroalloys use chromium, silicon.

Leading countries in ferroalloy production
- Currently, the production volume of global ferroalloys is 16.5 million tons per year, and according to the reports, these ferroalloys are fully meeting the production needs of all kinds of Steel (ordinary, special, structural) match. China, the United States and Japan are among the countries that are in the top position of ferroalloy production in the world. It is worth mentioning that ferroalloys are among the popular products whose production is a promising sign for industrial development. In expressing the environmental benefits of using ferroalloys, it is also necessary to explain that by adding ferroalloys during the steel melting process, the temperature of the furnace decreases, which reduces the intensity of energy production.
Types of ferroalloys
- In the following, some of the main types of these alloys are discussed:
Frusilis
- Ferrosilicon is a common type of ferroalloy that is used to prevent carbon loss during the production process of steel and iron alloys. In other words, ferrosilica is used as an essential alloy in the production of steel and cast iron. Ferrosilicon is also the basis for making magnesium prealloys such as magnesium ferrosilicon (FeSiMg). The main consumers of ferrosilicon are steel mills, followed by cast iron foundries.
ferrosilico calcium
- Ferrosilico calcium is a composite alloy composed of silicon, calcium and iron elements, this ferroalloy is an ideal oxidizing compound and desulfurization agent. This ferroalloy is used to produce high quality steel, special steel and special alloys.
ferromanganese
- Ferromanganese is a ferroalloy consisting of iron, manganese and carbon! And it is produced by melting iron ore and manganese in blast furnaces. In this ferroalloy, the manganese content is between 30 and 80% and the carbon content is between 2 and 6%. It should be noted that ferromanganese is used to deal with the harmful effects of sulfur in the production of steel and cast iron.
Ferrosilico Manganese
- After ferrochrome, ferrosilicomanganese alloy is the most widely used ferroalloy in the world and as its name suggests, it is composed of iron, manganese and silicon. The most important application of this ferroalloy is related to deoxidation in steel production processes. Improving the hardness and resistance of steel as well as reducing impurities such as phosphorus, nitrogen and sulfur in the production steel can be counted as other reasons for using this ferroalloy in steelmaking furnaces.
ferrochrome
- Ferrochrome is used to provide corrosion resistance in stainless steels.
cast iron ingot
- Cast iron ingot is an alloy that is produced by melting those iron-carbon alloys whose carbon content is more than two percent. It should be noted that this alloy mainly contains 1 to 3% of silicon and 2 to 4% of carbon in terms of structure, and its main application is related to improving the performance of molten metal casting.
iron pellet
- Iron pellets are spheres and spherical products that contain iron, and their most important use is related to the use in steel and iron production industries. It should be noted that the use of pellets is usually preferred over the use of lump stone and iron ore powder, the most important reasons for which are the excellent metallurgical properties of pellets in blast furnaces, as well as their strength, shape and size.
Graphite electrode
- Graphite electrode is an electrically conductive material, whose most important properties are very high resistance to extreme temperatures. This is why graphite electrodes are among the standard tools to accelerate the melting process in the electric arc furnace. In other words, these electrodes, immersed in metal waste, act as a very strong heat source and can be used in many refining processes.
Sponge iron
- Sponge iron is a product produced from the direct recovery of iron ore! And in terms of structural elements, it has very large amounts of iron and also very small amounts of phosphorus and sulfur. In expressing the advantage of this iron compared to raw iron, it should be mentioned that sponge iron is a very important raw material in electric furnaces due to its higher iron content.
How to buy ferroalloys
- Finally, it is necessary to remember that if you need to buy different ferroalloys, such as ferromanganese, ferrosilis, etc., you can contact the iron ore sales experts. The consultants of this collection are among the expert engineers in the field of engineering sciences who can provide the necessary guidelines to buy the type of ferroalloy suitable for your application.
