Because of its high vanadium content, ferrovanadium 80 is primarily used as an alloying additive in metallurgy to improve the mechanical properties of other metals, especially steel and cast iron.

1. High-Strength Low-Alloy (HSLA) Steels

   • Added to structural steels to increase strength, toughness, and resistance to fatigue and impact loading. Used in pipelines, bridges, automotive chassis, and construction.

2. Tool Steels & High-Speed Steels

   • Improves wear resistance, hardness, and high‑temperature strength of drill bits, cutting tools, dies, and molds.

3. Steel for Aerospace & Defense

   • Enhances performance of landing gear, armor plate, and aircraft components where high strength‑to‑weight ratio and toughness are critical.

4. Cast Iron Alloying

   • Increases tensile strength and wear resistance of nodular (ductile) cast iron and alloy cast irons used in automotive powertrains and heavy machinery.

5. Specialty Alloys

   • Used in manufacturing certain nickel‑base superalloys and titanium alloys where vanadium contributes to high-temperature stability and strength.

6. Vanadium Redox Flow Batteries (VRFB)

   • While not a direct use of FeV80, the high‑purity vanadium extracted from such alloys can be used in energy storage systems; however, this is a secondary market compared to metallurgy.

• Higher vanadium content means less alloy is needed to achieve target properties, improving cost efficiency in production.

• Produces cleaner steel with fewer inclusions when added in controlled amounts.
