Product Introduction
10-50mm Alloy 65% Ferro Silicon Granule Description
FeSi65 10–50mm is a ferrosilicon alloy used for regular steelmaking, foundry production and medium silicon addition. With Si 65% min, it gives more silicon input than FeSi45, but it is not as high as FeSi72 or FeSi75. This makes it a practical grade when your production needs balanced silicon addition, cost control and stable furnace feeding.
You may choose fesi65 when your process needs general silicon adjustment, steelmaking deoxidation support, foundry batching or cast iron production. It is suitable when your plant does not need high silicon addition like FeSi75, but still needs a reliable Fe-Si alloy source for regular production.
We supply ferro silicon 65% in 10–50mm, 10–100mm and custom sizes. Before shipment, we help you confirm Si content, Al, Ca, C, P, S, lump size, fines condition, 1MT jumbo bag packing, COA, MSDS, shipping marks and export documents. If your plant has fixed limits for Al, Ca, P or S, you can send us your internal standard before quotation.

Why FeSi65 Is Different From FeSi45, FeSi72 and FeSi75
FeSi65 should not be written as a lower version of FeSi72 or FeSi75. It has its own use value. You can choose FeSi65 when your production needs a medium silicon input instead of very low or very high silicon addition.
Compared with FeSi45, FeSi65 provides higher silicon content and is more suitable for regular steelmaking and foundry use. Compared with FeSi72 or FeSi75, FeSi65 can be more practical when your process does not require strong final deoxidation or high silicon correction.
| Grade | Si Content | Better Use Direction | Selection Focus |
|---|---|---|---|
| FeSi45 | 45% Min | Lower silicon input, cost-controlled metallurgical addition | Cost control and moderate formula adjustment |
| FeSi65 | 65% Min | Regular steelmaking, foundry use and medium silicon addition | Balanced Si input, cost and furnace practice |
| FeSi72 | 72% Min | Steel deoxidation and alloy addition | Stronger deoxidation and Si adjustment |
| FeSi75 | 75% Min | High silicon addition and final deoxidation | Higher Si recovery and lower addition amount |
FeSi65 is useful when your plant needs a flexible grade between low-silicon and high-silicon ferro silicon. Your final choice should follow your steel grade, foundry formula, silicon target and cost plan.

FAQ
Q: What is FeSi65 ferro silicon used for?
A: FeSi65 ferro silicon is used for regular steelmaking, foundry production, medium silicon addition, furnace feeding and general metallurgical alloy use.
Q: What is the silicon content of FeSi65?
A: FeSi65 usually contains Si 65% min. Your team can check actual Si, Al, Ca, C, P and S values by batch COA before shipment.
Q: What is the difference between FeSi65 and FeSi72?
A: FeSi65 has lower silicon content and is more suitable for medium silicon addition and regular foundry or steelmaking use. FeSi72 is usually selected when stronger steel deoxidation or higher silicon addition is required.
Q: How is FeSi65 packed for export?
A: Standard export packing is usually 1MT jumbo bag. Small bags, pallet packing, custom shipping marks, COA, MSDS and loading photos can be arranged according to your order.
