Product Introduction
FeSi45 Ferro Silicon Alloy Lumps Description
Ferrosilicon 45 (FeSi45) lump is a common ferrosilicon product belonging to iron-silicon alloy material.
It mainly consists of silicon and iron, with silicon content between 40% and 47%, and iron taking up the rest proportion. Trace elements including Al, Ca, Mn, Cr, P, S and C are strictly controlled to ensure stable service performance.
This low-silicon ferrosilicon grade applies to basic alloy adjustment and flexible furnace burden batching. It suits cost-efficient metallurgical production that does not need high silicon addition.
Available in lump form, this ferrosilicon simplifies weighing, storage and furnace feeding, lowers material loss and lifts overall smelting efficiency.

FAQ
Q:What are Ferro Silicon 45 lumps used for?
A:Ferro Silicon 45 lumps are used for low silicon alloy addition, basic metallurgical use and furnace material adjustment. This grade is suitable when your process needs lower silicon input than FeSi65, FeSi70 or FeSi72.
Q:What is the silicon content of FeSi45?
A:FeSi45 usually contains 40–47% silicon, with iron as the balance element. Al, Ca, Mn, Cr, P, S and C are also controlled according to the required specification.
Q:What is the difference between FeSi45 and FeSi65?
A:FeSi45 has lower silicon content, usually 40–47% Si, while FeSi65 contains about 65% Si. FeSi45 is more suitable for lower silicon input and basic alloy addition. FeSi65 is selected when your process needs a higher silicon level.
Q:Is Ferro Silicon 45 suitable for furnace addition?
A:Yes. Ferro Silicon 45 lumps can be used for regular furnace addition. The lump form is easier to weigh, store and charge than excessive fine powder.
Q:What lump size can you supply?
A:Common sizes include 10–50mm and 10–100mm. We can also confirm customized size according to your furnace operation, storage condition and handling requirement.
Q:What should I check before buying FeSi45?
A:You should check Si content, Al, Ca, Mn, Cr, P, S, C, lump size, powder ratio, packing method, COA and MSDS. If you have a target formula or application, you can send it to us before quotation.
Q:How do you pack Ferro Silicon 45 for export?
A:Ferro Silicon 45 lumps are usually packed in 1 MT FIBC jumbo bags. Waterproof bags or customized export packing can be confirmed according to your destination, storage condition and shipment requirement.
Q:Can you provide COA and MSDS?
A:Yes. We can provide COA, MSDS, invoice, packing list and shipping documents according to your order requirement. You can confirm chemical composition and packing details before shipment.
