What are the categories of ferrotitanium?
Ferrotitanium is an alloy whose main components are titanium and iron. According to different production processes and uses, ferrotitanium can be divided into many different categories. The following are some of the main categories of ferrotitanium:

1. Nitrided ferrotitanium: This type of ferrotitanium contains nitrogen and is mainly used to make high-strength and wear-resistant alloy materials, such as wear-resistant steel, stainless steel, etc.

2. Silicon-titanium ferro: This titanium-iron contains silicon and is mainly used to make wear-resistant and corrosion-resistant alloy materials. It can also be used to produce steel and stainless steel.

3. Niobium-titanium ferro: This titanium-iron contains niobium and is mainly used to improve the grain refinement and strengthening effect of steel, and improve the hardness and wear resistance of the alloy.

4. Vanadium-titanium ferro: This titanium-iron contains vanadium and is mainly used to produce high-strength alloy steel and stainless steel, with good thermal strength and wear resistance.

5. Chromium-titanium ferro: This titanium-iron contains chromium and is mainly used to produce stainless steel and high-temperature alloy materials, with good corrosion resistance and high temperature resistance.

6. Tungsten-titanium ferro: This titanium-iron contains tungsten and is mainly used to make high-strength and wear-resistant alloy materials. It is widely used in aerospace, automobile manufacturing and other fields.

In general, titanium-iron is an important alloy material with broad application prospects. Different types of titanium-iron have unique advantages and uses in different fields, which can meet the needs of different industries. In the future development, titanium-iron alloy will continue to play its important role and promote the development and progress of all walks of life.
