1. Aerospace industry
Vanadium-titanium alloys are widely used in aircraft engines, aerospace cabin skeletons, missiles, hydrofoils and introducers of warships, steam turbine blades, rocket engine casings, etc. In addition, vanadium alloys are also used in magnetic materials, hard alloys, C-conducting materials and nuclear reactor materials.

2. Steel industry
About 85% of metallic vanadium is added to steel production in the form of ferrovanadium and vanadium-nitrogen alloys to improve the strength, toughness, ductility and heat resistance of steel. Vanadium-containing high-strength alloy steel is widely used in the production and construction of oil/gas pipelines, buildings, bridges, and rails. Vanadium-containing high-strength alloy steel mainly includes: high-strength low-alloy (HSLA) steel (comprehensive); HSLA steel plate; HSLA section steel; HSLA strip steel; advanced high-strength strip steel; and die steel, etc.
3. Chemical industry
In the chemical industry, vanadium compounds are used in catalysts, ceramic colorants, developers, desiccants and raw materials for the production of high-purity vanadium oxide or ferrovanadium. V205 has special activity as a catalyst, and other elements are difficult to replace.
