Ferro Silicon Lumps 72 Grade Metallurgical Product for Foundry and Steel Production Applications

Ferro Silicon 72 grade lumps are a versatile metallurgical product tailored for foundries and steel plants, bridging the gap between high-purity alloys and cost-sensitive applications. With a balanced silicon content of ≈72%, they deliver effective deoxidation--removing oxygen to prevent porosity and weak welds in castings, and refining grain structure for stronger steel billets.

In foundries, they improve mold filling and reduce shrinkage defects, critical for producing complex automotive parts or industrial machinery components. For steel production, they enhance alloy uniformity, boosting yield strength and fatigue resistance in rails, beams, and pressure vessels.

The lump form ensures slow, controlled melting, minimizing splashing and promoting even mixing with molten metal. Compared to higher-grade FeSi 75, Grade 72 offers a cost advantage without sacrificing core functionality, making it ideal for mid-tier manufacturing. Its compatibility with both ferrous and non-ferrous systems expands utility, while stable supply chains ensure consistent availability.
