What Is The Melting Point Of Ferro Vanadium?

What is the melting point of ferro vanadium?

The melting point of ferro vanadium (FeV) varies depending on its vanadium content, as vanadium has a much higher melting point (1,890°C) than iron (1,538°C). Commercially available FeV alloys typically contain 40–80% vanadium by weight, with higher vanadium concentrations raising the alloy's melting point.

For example, FeV50 (50% V, 50% Fe) has a melting range of approximately 1,540–1,580°C, slightly above iron's melting point due to vanadium's influence. In contrast, FeV80 (80% V, 20% Fe) exhibits a significantly higher melting point, around 1,700–1,750°C, approaching vanadium's pure melting point. Ultra-high-purity grades (e.g., 90% V) may have melting points exceeding 1,800°C, nearing vanadium's intrinsic value.

This variability is critical for processing: lower-vanadium FeV alloys are often produced via carbothermal reduction in electric arc furnaces (1,600–1,800°C), where molten iron and vanadium oxide are reduced and mixed. Higher-vanadium grades, such as those made via aluminothermic reduction, benefit from exothermic reactions that generate sufficient heat (up to 2,500°C) to melt the alloy without external heating. Understanding these melting ranges is essential for casting, forging, and alloying processes to ensure optimal product quality and performance.
