Premium Silicon Metal 441/553 Lump for Aluminum Alloys

High-purity silicon metal lumps with 441/553 grade composition, ideal for aluminum ingot production and metallurgical applications. Exceptional consistency in silicon content (98.5%-99.3%) ensures precise alloy strength and corrosion resistance.

Specially processed lump form promotes efficient melting with minimal slag, reducing energy consumption in smelting. Low trace elements (Fe, Al, Ca) meet strict industrial standards for aerospace-grade aluminum alloys.

Primary applications include automotive parts, solar panel frames, and construction materials manufacturing. Bulk packaging available for foundries seeking cost-effective raw materials without compromising quality.

Globally sourced, factory-direct pricing with volume discounts for industrial buyers. Custom particle size options upon request to match specific furnace requirements.
