FeSi70 Alloy for Controlled Metallurgical Addition

FeSi70 Alloy is a ferro silicon alloy used when your production needs controlled metallurgical addition, regular silicon input and stable alloy composition adjustment. With Si 70% min, this grade provides higher silicon input than FeSi65, while remaining more moderate than FeSi72 or FeSi75 when your process does not need stronger high-silicon addition.

You can use FeSi70 in steelmaking, foundry production and metallurgical batching when your process needs a practical silicon source with confirmed impurity values. This page focuses on controlled addition rather than only describing FeSi70 as a general deoxidizer. In real production, the value of FeSi70 comes from stable grade chemistry, suitable size range, controlled fines condition and clear batch COA.

We supply FeSi70 alloy in lump, granule and custom size ranges according to your furnace feeding, ladle addition or foundry batching method. Before shipment, we help confirm Si content, Al, Ca, C, P, S, size range, fines condition, COA, MSDS, packing method, shipping marks and export documents. If your plant has fixed limits for impurities or size tolerance, you can send us your internal standard before quotation.

Q: What is FeSi70 alloy used for?
A: FeSi70 alloy is used for controlled metallurgical addition, steelmaking deoxidation support, foundry silicon adjustment and alloy composition control.

Q: What is the silicon content of FeSi70?
A: FeSi70 usually contains Si 70% min. Actual Si, Al, Ca, C, P and S values should be checked by batch COA before shipment.

Q: What is the difference between FeSi65 and FeSi70?
A: FeSi70 provides higher silicon input than FeSi65. It can be selected when medium silicon input is not enough and the process needs stronger controlled addition.

Q: What is the difference between FeSi70 and FeSi72?
A: FeSi72 provides slightly higher silicon input than FeSi70 and is more suitable when your process needs stronger Si contribution. FeSi70 is more moderate for regular controlled metallurgical addition.

Q: What should be confirmed before ordering FeSi70?
A: You should confirm Si content, Al/Ca/C/P/S limits, size range, fines condition, packing method, COA requirement, order quantity and destination port.
