Ferroalloys are not metal materials that can be used directly, but are mainly used as raw materials for deoxidizers, reducing agents and alloy additives in iron and steel production and foundry industries. With the development of modern science and technology, various industries have higher and higher requirements for the variety and performance of steel, which also puts forward higher requirements for ferroalloys. There are many varieties of ferroalloys, and there are many classification methods. This article mainly introduces ferroalloys, the classification of ferroalloys, the similarities and differences between ferroalloys understood internationally and ferroalloys understood by the Chinese market.

Ferro Alloys Meaning 

Generally, ferroalloys are considered to be alloys made of one or more metal or non-metal elements and iron elements. For example, ferrosilicon is Fe2Si, Fe5Si3, FeSi, FeSi2 and other silicides formed by silicon and iron. Ferro manganese is an alloy of manganese and iron, which also contains a small amount of other elements such as carbon, silicon, and phosphorus. Ferro chrome alloys containing sufficient silicon are called silicon-manganese alloys. Ferrochrome is an alloy of chrome and iron, which also contains a small amount of other elements such as carbon, silicon, and phosphorus.

In China, especially in Anyang, the hometown of ferroalloys, ferroalloy refers to a product that is added to molten iron as a deoxidizer, element additive, etc. during steelmaking to make the steel have certain characteristics or meet certain requirements. A master alloy composed of iron and one or several elements, mainly used in iron and steel smelting. In the iron and steel industry, all intermediate alloys used in steelmaking are generally referred to as “ferroalloys” regardless of whether they contain iron (such as silicon calcium alloys). It is also include some pure metal additives and oxide additives. Therefore, if you want to purchase pure metals such as pure calcium metal, silicon metal, electrolytic manganese metal, and carbon raiser, it is a good choice to find ferroalloy suppliers.

Types of Ferro Alloys

With the development of modern science and technology, various industries have higher and higher requirements for the variety and performance of steel, which also puts forward higher requirements for ferroalloys. There are many varieties of ferroalloys, and there are many classification methods. Generally, they are classified according to the following methods:

(1) According to the main elements in ferroalloys, it can be divided into ferro silicon, ferro manganese, ferro chrome, ferrov anadium, ferro titanium, ferro tungsten, ferro molybdenum and other ferroalloys.

(2) According to the carbon content in the ferroalloy, it can be divided into high carbon, medium carbon, low carbon, micro carbon, ultra micro carbon and other varieties. Carbon content of 4-8% is a high carbon alloy. Carbon content of 1-2% is a medium carbon alloy. Carbon content of 0.1-1% is a low carbon alloy. Carbon content below 0.1% is a micro carbon ferro alloy.

(3) According to the production method, it can be divided into blast furnace ferroalloys, electric furnace ferroalloys, out-of-furnace (metal thermal) ferroalloys, vacuum solid-state reduction ferroalloys, converter ferroalloys, electrolytic ferroalloys, etc. In addition, there are special iron alloys such as oxide compacts and heat-generating iron alloys.

(4) According to the classification of two or more alloying elements contained in multi-component iron alloys, the main varieties are silicon aluminum alloy, silicon calcium alloy, silicon manganese aluminum alloy, silicon calcium aluminum alloy, silicon calcium barium alloy, and silicon aluminum barium calcium alloy, etc.

Ferrosilicon, ferromanganese, and ferrochromium are the three most consumed ferroalloys.

ZXferroalloy is a leading manufacturer of ferroalloy. The main products we produced are nitride ferro chrome, nitride ferrosilicon, nitride ferro manganese, and nitride silicon manganese.
