Ferrosilicon Zirconium FeSiZr Lump Supply
Ferrosilicon Zirconium, also called Ferro Silicon Zirconium or FeSiZr, is a ferroalloy made from silicon, zirconium and iron. It is supplied for foundry and selected steelmaking applications where both silicon and zirconium addition are required.
Our FeSiZr Alloy is supplied as 10-60mm lump, which is easier to handle than fine powder during foundry charging. This size is suitable for bulk addition, furnace feeding and export packing in 1MT jumbo bags.
For foundry use, FeSiZr can be used in inoculation-related treatment, molten metal conditioning and graphite structure control under suitable casting conditions. The final effect depends on your iron grade, furnace practice, addition method and confirmed Si/Zr ratio.
For your order, we can confirm Si and Zr content, impurity limits, lump size, COA, MSDS, packing list and inspection documents before shipment.

FeSiZr Grade Selection for Foundry Use
Not every Ferrosilicon Zirconium grade is selected in the same way for foundry use. For common foundry charging and inoculation-related treatment, buyers usually pay more attention to the Si/Zr ratio, lump size, addition method and COA stability.
Lower and medium Zr grades are easier to match with regular foundry processes. Higher Zr grades can also be supplied, but they should be confirmed according to the required zirconium addition, casting process and final COA requirement.
| Grade Range | Foundry Use Recommendation | Purchase Note |
|---|---|---|
| FeSiZr1.5-2 | Suitable for common cast iron treatment and inoculation-related use | Good for lower Zr addition requirements |
| FeSiZr10 | Suitable for foundry and selected steelmaking use | Common choice when moderate Zr addition is required |
| FeSiZr15 | Suitable for foundry molten metal treatment | Si/Zr ratio should be confirmed before order |
| FeSiZr20 / FeSiZr25 | Suitable when higher Zr addition is required | Recommended after checking casting process and COA |
| FeSiZr30 and above | Special foundry or steelmaking use | Not a regular foundry choice unless the buyer has clear Zr requirements |
| ZrSiFe50 | Special high-Zr requirement | Should not be used as a general foundry inoculant without process confirmation |
For this product page, we mainly focus on Ferrosilicon Zirconium FeSiZr Lump 10-60mm for foundry charging. If your process requires a higher Zr grade, we can confirm whether it is suitable according to your casting condition and COA requirement.

FAQ
Q:What is Ferrosilicon Zirconium FeSiZr Lump?
A:Ferrosilicon Zirconium FeSiZr Lump is a silicon-zirconium ferroalloy supplied in lump form. It mainly contains silicon, zirconium and iron, and is used for foundry charging, molten metal treatment and selected steelmaking applications.
Q:Is 10-60mm FeSiZr Lump suitable for foundry use?
A:Yes. 10-60mm lump is suitable for foundry charging because it is easier to handle than fine powder and can reduce dust loss during bulk addition. The final size tolerance should be confirmed before shipment.
Q:Are all FeSiZr grades suitable for foundry use?
A:Not in the same way. Lower and medium Zr grades are more commonly used in foundry applications, while higher Zr grades should be confirmed according to the required Zr addition, casting process and COA.
Q:Can Si and Zr content be customized?
A:Yes. Si/Zr ratio can be confirmed according to your casting process, furnace practice and purchase requirement. The final composition should follow the confirmed contract and COA.
