Ferro Niobium
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 of 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.
