Lead-Antimony (Sb) Alloys
Hard, durable lead-antimony alloys blended in-house to your percentage spec — for battery grids, machinery, and bullet casting. Elemental analysis on every shipment.
Hardness and durability, blended to spec
Pure lead is soft. Adding antimony (Sb) hardens it and improves its casting properties, producing an alloy that holds up under mechanical stress and casts cleanly into precise shapes. That combination of strength and durability makes lead-antimony one of the most widely used lead alloys in industry.
We blend lead-antimony alloys in-house to your percentage specification, so you get the exact hardness and characteristics your application calls for — whether that's battery grids, machinery components, or bullet casting.
Every batch is quality-checked to international standards and ships with elemental analysis. We source responsibly and prioritize recycling, keeping environmental impact low at every stage.
