FeSi70 Ferro Silicon 50–100mm for Balanced Silicon Addition

Ferrosilicon serves as a mainstream iron-silicon alloy widely adopted in regular steelmaking and foundry production for melt deoxidation and element adjustment. Among common specifications, FeSi70 ferro silicon with 50–100mm lump size is well suited for steady silicon supplementation and conventional furnace feeding work.

It features a minimum 70% silicon content, offering stronger silicon releasing capacity than FeSi65, while keeping its performance more moderate compared with high-purity FeSi72 and FeSi75 grades.

This grade is ideal for production processes that demand more sufficient silicon supplement than FeSi65, yet do not require ultra-high silicon strength for final deoxidation and ladle refining. Its large lump specification perfectly matches bulk feeding operation in most industrial furnaces.

We can provide FeSi70 in 50–100mm, 10–100mm and other customized particle sizes. Before delivery, we will fully inspect core indicators including silicon content, aluminum, calcium, carbon, phosphorus and sulfur impurities, as well as lump uniformity and fine powder proportion. Complete documents such as COA, MSDS and full set of export papers can also be arranged properly. If your workshop has clear internal standards on impurity limitation and particle size range, you may advance your technical requirements to achieve fully matched material delivery.

Q: What is FeSi70 ferro silicon 50–100mm used for?
A: FeSi70 ferro silicon 50–100mm is used for balanced silicon addition, metallurgical deoxidation support, furnace use and alloy adjustment when your process accepts larger lump material.

Q: What is the silicon content of FeSi70?
A: FeSi70 usually contains Si 70% 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 FeSi70 and FeSi65?
A: FeSi70 provides higher silicon input than FeSi65. It can be checked when FeSi65 is not enough, but FeSi72 or FeSi75 is not necessary.

Q: How is FeSi70 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.
