FAQ

Q: What is FeSi used for?

A: Ferrosilicon (FeSi) is an alloy of iron and silicon with a very variable silicon content between 10% and 90%. It is used as a so-called master alloy in steel production, which is added in small amounts in order to adjust the properties of the melt, the cooling process and the finished product.

Q: What is the melting point of FeSi?

A: The melting point of ferro silicon varies with the silicon content: FeSi 75%: Melting point ranges between 1,210 – 1,300°C (2,210 – 2,370°F). FeSi 90%: Melting point is higher, around 1,350°C (2,460°F).

Q: Is FeSi magnetic?

A: FeSi is a paramagnetic, and CoSi is a diamagnetic, but solid solutions of Fe1-xCoxSi (x ≥ 0.1) are helical ferromagnetic.

Q: Can ferrite be recycled?

A: Despite their widespread use, ferrite magnets present an interesting recycling paradox: while inexpensive to produce from virgin materials, they are costly to recycle. The economic challenge stems from the low market value of the recovered materials compared to the energy and processing costs required for recycling.

Q: Which industries commonly use ferrosilicon?

A: Our products are widely used in steelmaking, iron casting, ferroalloy production, welding material manufacturing, and refractory industries.

Q: Can I order samples before bulk purchasing?

A: Yes. Sample availability depends on the product specification and quantity required.

Q: Can you provide quality inspection reports?

A: Yes. Chemical composition reports, inspection records, and other documentation can be supplied according to customer requirements.

Q: What is your minimum order quantity?

A: MOQ depends on the product specification, customization requirements, and packaging method. Please contact us for detailed information.

Q: How long is the production lead time?

A: Production time varies according to product grade, order quantity, and production schedule. We will provide an estimated delivery time after confirming the order.

Q: Which countries do you export to?

A: Our products are supplied to customers across Asia, Europe, the Middle East, South America, Africa, and other international markets.

Q: Which shipping methods are available?

A: We arrange shipments by sea, rail, truck, or air according to customer requirements and destination.
