FeZr80 Lumps of defined size 80% Zr balance Fe


The ferro-zirconium 80% master alloy is employed in the ferrous metal industry. Zirconium is a strong grain refiner and denitrifier, a powerful deoxidizer and also acts as an excellent sulfide shape controller. Appropriate additions of zirconium enhance impact resistance, yield strength and the hardenability of steels.

In addition, the alloy can be utilized as a zirconium additive and serves as a beneficial trace element in cobalt and nickel-based super alloys wherein iron does not have a detrimental influence.

Applications of FeZr Master Alloys

  • FeZr serves as a grain refiner in steel and cast iron
  • FeZr is used in carbide formation, desulphurisation, deoxidation, nitrogen scavenging
