Niobium

Niobium Is An Alloy,Which Is Formed By Combining Iron And Niobium With A Niobium Content Range Of 60-70%.Niobium Is The Number One Alloy Agent Used For High-Strength Low-Alloy Steel And Its Also Has Captured 80% Of The World Market. Niobium Is An Additive To The Product Of Amprphous Metals, And Will Impart Several Desirable Properties Upon The Resulting Compound. One Of The Primarily Benefits Of Adding Niobium To An Alloy Is In Its Anti-Corrosion Properties(Better Than Carbon Steel). Additionally, The Adding Of Niobium To An Alloy Can Make It More Weldable And Much Stronger. With The Addition Of Other Elements Such As Zirconium,Ferro Niobium Is Perfectly Produced For Directionally Sensitive Applications Such As Suspension Bridges As Ferro Niobium Increases High Temperature Resistance,Corrosion Resistance,Oxidation Resistance, As Well As Reducing Erosion At High Temperature.
