Ferro Silicon Zirconium (FeSiZr) is a ferroalloy composed of zirconium (Zr), silicon (Si), and iron (Fe). It is primarily used as a deoxidizer, grain refiner, and inoculant in steel and foundry industries. The addition of zirconium enhances mechanical strength, toughness, and corrosion resistance in special steel and cast iron applications.


Chemical Composition:

✅ Zirconium (Zr): 15-40% (varies by grade)

✅ Silicon (Si): 40-50%

✅ Iron (Fe): Balance

✅ Carbon (C): ≤ 0.1%

✅ Sulfur (S): ≤ 0.03%

✅ Phosphorus (P): ≤ 0.03%

Key Features:

✅ Powerful Deoxidizer & Inoculant: Improves steel purity by removing oxygen.

✅ Grain Refiner: Enhances strength, hardness, and wear resistance.

✅ Improves Steel & Cast Iron Properties: Increases toughness and corrosion resistance.

✅ Available in Various Sizes: Supplied as lumps, granules, or powder.

Applications:

✅ Steel & Foundry Industry: Used in high-strength, low-alloy (HSLA) steels.

✅ Cast Iron Production: Enhances machinability and surface quality.

✅ Specialty Alloys & Superalloys: Improves mechanical properties in aerospace and automotive applications.

✅ Welding Electrode Manufacturing: Enhances arc stability and weldability.
