Product Introduction
Impurity-Controlled FeSi 75 Lump: What It Means for Your Purchase
Our refined FeSi 75 lumps are supplied as a precisely screened 50–100 mm grade, engineered to deliver consistent silicon content and strictly controlled impurity levels. We maintain aluminum content at ≤ 0.5%, alongside tight limits on sulfur and phosphorus-all to promote cleaner melting processes and reliable production outcomes.
Boasting uniform particle size and robust mechanical strength, this ferrosilicon grade feeds smoothly into furnaces and resists damage during loading and transit. This minimizes breakage and fine particle formation, a common pain point for many metallurgical operations.

FAQ - Quality Control, Logistics and Foundry Support
Q：How do you define "tight impurity control" for FeSi 75
A：Impurity limits are managed to agreed thresholds, and each batch is verified by composition testing before shipment.
Q：How is the 50–100 mm range maintained during production
A：Material is screened by size, and off-size pieces and fines are separated to keep the lump range consistent.
Q：What service support is available during ordering
A：We provide batch documentation, packing confirmation and coordination on shipping schedules and destination requirements.
