Ferro Niobium (FeNb) is an important iron-niobium alloy, with a niobium content of 60-70%.  FeNb is manufactured in an electric furnace by the aluminothermy method. It contains about 60-70% niobium.

It is used in the smelting of heat resistant alloys. It is used in increasing the strength of the alloys, including manufacturing of High-Strength special Steels Low-Alloy, mainly used in automobiles, pipe fabrication, structural steels and stainless steels resistant to high temperatures.

Applications
Some of ferro niobium alloy's applicaitons are found in automobiles, during alloy production, defensive machines used by army.
