Ferroniobium an iron alloy with niobium and iron as its principal components. It also contains impurities such as aluminum, silicon, carbon, sulfur and phosphorus. According to the content of niobium alloy is divided into FeNb50, FeNb60, FeNb70. The iron alloy produced from niobium tantalum contains tantalum and is called niobium tantalum iron. Iron niobium and niobium-nickel alloys are used as niobium additives for iron and nickel alloys in vacuum smelting. Require low gas content, low harmful impurities, such As Pb, Sb, Bi, Sn, As, etc. 2Ã??10-6, so the title "VQ"(vacuum mass), such as VQFeNb, VQNiNb and so on. The niobium-ferromanganese alloy produced in China (NB10% ~ 15%) is used as alloying agent for low alloy steel and niobium treatment agent for carbon steel.
