Off-Grade Silicon Metal 90% Si

Off-Grade Silicon Metal 90% Si - Cost-Effective Deoxidizer for Steelmaking (10-50mm)

1.Product Summary

Looking for a reliable, budget-friendly alternative to standard ferrosilicon? Our Off-Grade Silicon Metal (Si ≥90%) delivers stable deoxidation performance at a fraction of the cost. Widely used by steel mills and foundries across Southeast Asia, the Middle East, and Africa, it's the smart choice for cost-conscious buyers who don't want to compromise on quality.

2.Product Description

Our Off-Grade Silicon Metal (Si ≥90%) is not "substandard" - it's high-value industrial silicon​ engineered for steel plants and foundries that need consistent deoxidation and alloy trimming without the premium price tag of standard silicon metal grades. With controllable chemistry (Al, C, S, P all within tight ranges), uniform 10-50mm lump sizing, and minimal fines, it charges smoothly and reduces material loss. Many of our clients have replaced part of their FeSi75 consumption with our Si90 off-grade material, cutting alloy cost per ton of steel by 15%–30%. Every batch ships with a Mill Test Certificate, and SGS/BV third-party inspection is available on request. With 2,000 MT monthly capacity, long-term stock, and both FOB and CIF terms, we keep your production line running without interruption.

Non-Standard Silicon Metal Lumps (Si ≥90%) - Ideal Substitute for Ferrosilicon in Steel & Foundry

1.Product Summary

Industrial Grade Off-Grade Silicon - Deoxidizer & Alloying Additive for Steel, Customizable Size & Spec

1. Product Summary

One size doesn't fit all. That's why our Industrial Grade Off-Grade Silicon (Si ≥90%) comes with full customization - from particle size to chemical composition. Whether you need 10-30mm for electric arc furnaces or 30-50mm for BOF applications, we tailor the product to your process requirements and budget.

2.Product Description

Our Industrial Grade Off-Grade Silicon is built around flexibility and performance. With Si content ≥90% and tightly controlled impurities (Al ≤1.5%, C ≤0.5%, S ≤0.05%, P ≤0.05%), it performs reliably as a deoxidizer, slag conditioner, and Si-trimming agent in carbon steel, low-alloy steel, and cast iron production. Unlike rigid "standard grades," we work with you to adjust sizing, packaging, and chemistry to fit your specific furnace setup and cost targets. With 2,000 MT monthly capacity, spot stock, ISO 9001 certification, and full export documentation (MTC, SGS/BV), we make international procurement simple and low-risk. MOQ from 20 MT, T/T and L/C accepted.
