Ferroniobium is an important iron niobium alloy, with a niobium content of 60 to 70 percent. It is the main source for niobium alloying of HSLA steel and covers more than 80 percent of the world wide niobium production. The niobium is mined from pyrochlore deposits and is subsequently transformed into the niobium pentoxide Nb2O5. This oxide is mixed with iron oxide and aluminium and is reduced in an aluminothermic reaction to niobium and iron. The ferroniobium can be purified by electron beam melting or used as it is. For alloying with steel the ferroniobium is added to molten steel before casting.
Features:
1. High Quality FeCb alloy concentrate is used as material to manufacture FeNb60-B and FeNb20.
2. High Quality FeCb alloy is delivered in lump or powder.
3. The quality of the biggest particle does not exceed 8kg. The quality of this product whose particle size range is less than 20mm×20mm should not exceed 5% of the total quality.

Appications:
High Quality FeNb alloy is applied to steel making and foundry as
additive. We add niobium to stainless and heat resistant steel so
as to raise its plasticity and corrosion resistance of your
product. We add niobium to structural steel to improve welding
property of the structural steel and enhance its strength and
plasticity to prevent welding seam from corrosion. Niobium is
indispensable to high temperature steel and alloy, since niobium
can enhance high temperature strength, refine grain and avoid grain
growth. Carbide which is made by Niobium is combined with carbon
can eliminate harmful effects that chromium carbide deposits in
stainless steel to enhance abrasion resistance of
steel.Mn : 40-70%
