What Is Ferrotitanium?
Ferrotitanium (FeTi) is a ferroalloy mainly composed of titanium and iron. Titanium has a strong affinity for oxygen, nitrogen and carbon, making FeTi useful when controlled titanium addition is required during steel production.
In steelmaking, ferrotitanium is commonly added during alloying or refining to introduce titanium into molten steel. The addition level and recovery depend on titanium content, particle size, steel grade and melting conditions.
FeTi is also used in stainless steel, specialty steels and other alloy systems where titanium content needs to be controlled within a specific range. Stable chemical composition is especially important for consistent metallurgical results.
Ferrotitanium Grades and Chemical Composition
Ferrotitanium grades are mainly classified according to titanium content and chemical composition. Common grades include FeTi130-A, FeTi130-B, FeTi140-A and FeTi140-B, with Ti content generally ranging from 25% to 45%.
| Grade | Ti Content | Main Difference |
| FeTi130-A | 25–35% | Lower Si and controlled impurities |
| FeTi130-B | 25–35% | Slightly higher Si |
| FeTi140-A | 35–45% | Higher Ti with lower Si |
| FeTi140-B | 35–45% | Higher Ti with slightly higher Si |
The main difference between these grades is the Ti range and limits for elements such as Si, C, P and S. The appropriate grade should be selected according to the target steel composition and required titanium addition.
For buyers, stable chemical composition is more important than simply choosing a higher Ti grade. Ti recovery, impurity limits and particle size should all be considered when determining the suitable FeTi specification.
Ferrotitanium Production Methods
Ferrotitanium can be produced through different reduction routes depending on the titanium-bearing raw materials, reducing agent and required alloy composition. Carbothermic reduction and aluminothermic reduction are two important production methods.
In the carbothermic route, titanium-containing raw materials are mixed with carbonaceous materials and reduced at high temperature. The main reduction reaction can be expressed as:
TiO₂ + C → Ti + CO
The process normally requires high-temperature electric furnace conditions. Control of raw material quality, reduction temperature and furnace operation is important for titanium recovery and final alloy composition.
In the aluminothermic route, aluminum is used as the reducing agent. The reduction of titanium oxide can be represented by:
3TiO₂ + 4Al → 3Ti + 2Al₂O₃
The reaction releases considerable heat and can be used to produce titanium-containing ferroalloys. The selection of raw materials and control of the reduction process directly affect the Ti content and impurity levels of the finished FeTi.
For industrial production, the choice of reduction method depends on the raw material composition, target Ti grade, impurity requirements and production conditions. Consistent process control is essential for maintaining stable chemical composition between batches.
How to Choose a Ferrotitanium Supplier?
For FeTi procurement, the appropriate grade should be selected according to the steelmaking process and the required titanium addition. Ti range, C/P/S limits, Al and Si content should be confirmed before placing an order.
A reliable supply should also provide consistent chemistry between batches, suitable sizing and packing, and complete quality documentation such as TDS, COA and inspection reports when required.
