Ferrosilicon is an alloy of silicon and iron. By utilizing its powerful chemical affinity with oxygen, ferrosilicon can be mainly used as deoxidizer in the process of steelmaking. Ferrosilicon is also used as silicon additive and as a foundry inoculant to increase the strength of steel.

Origin: Brazil, China, Kazakhstan, etc.

Material: Silica stone, reducing agent, mill scale as steel additive

Silicomanganese is an alloy of manganese, silicon, and iron. Silicomanganese is used as an agent to remove oxygen and sulfur from molten steel in the steelmaking process, and also for adding manganese and silicon. Especially, low carbon silicomanganese contains a high silicon and low carbon content, and is mainly used for governing the quality of stainless steel that contain a lot of manganese.

Origin: India, Brazil, Ukraine, etc.

Material: Manganese ore, silica stone

Ferrotitanium is an alloy of titanium and iron. Ferrotitanium has a high affinity with oxygen, nitrogen, and sulfur and is mainly used for deoxidization during the process of steel smelting.

Origin: Great Britain

Material: Titanium and steel scraps

Ferrochrome is an alloy of chrome and iron. Ferrochrome is mainly used as a material for stainless steel which is defined as alloy steel with a minimum of 10.5% chrome. Ferrochrome also has the property to strengthen corrosion and abrasion resistance, and is widely used for producing heat-resistant steel, structural steel (buildings, ships, etc.), and high tensile strength steel (buildings, bridges, etc.). Ferrochrome is largely classified into 3 types depending on the carbon content.

Origin: South Africa, Europe, China, India, etc.

Material: Chrome ore, reducing agent, silica stone. etc.

Ferronickel is a ferroalloy containing nickel and iron, and is typically used in stainless or special steel. By adding nickel, it is possible to increase heat resistance, durability, toughness, and hardenability. Therefore, ferronickel is used for structural alloy steel, heat-resistant steel, and alloy tool steel.

Origin: Japan, Brazil, etc.

Material: Nickel ore, limestone, coal

Ferromolybdenum is a ferroalloy containing molybdenum and iron. It has a property to increase hardness, heat, and abrasion resistance, and is used as a material for structural steel, high tensile strength steel, and tool steel.

Origin: Korea, etc.

Material: Molybdenum concentrate

Ferrovanadium is a ferroalloy containing vanadium and iron. It has a property to increase toughness, heat, and corrosion resistance, and is used as a material for high tensile strength steel, structural steel, and tool steel.

Origin: Japan, Taiwan, Korea, etc.

Material: Vanadium pentoxide, spent catalyst
