Ferro Niobium

Ferro Niobium is a ferrous alloy of niobium and iron as its main components. It also contains impurities such as aluminum, silicon, carbon, sulfur and phosphorus. Depending on the amount of niobium contained in the alloy, it is divided into FeNb50, FeNb60, FeNb70. ferroalloys produced from niobium-tantalum ores contain tantalum and are called niobium-tantalum ferroalloys. Vacuum smelting of iron-based alloys and nickel-based alloys such as ferro-niobium and niobium-nickel alloys for niobium additives. Requirements for low gas content, low harmful impurities, such as Pb, Sb, Bi, Sn, As, etc. are <2 × 10, so the title "VQ" (vacuum quality), such as VQFeNb, VQNiNb and so on. China's production of niobium-manganese ferroalloys (Nb10% ~ 15%) used as a low-alloy steel alloying agent and carbon steel niobium treatment agent.
