Antimony — The Hardening Metal
Antimony (Sb) is a metalloid that dramatically increases the hardness and strength of lead when added in small percentages — this is the basis of all antimonial lead alloys used in battery grids, structural casting, and bearing metals. PSR Metals supplies pure antimony at 99.99% purity, giving lead-alloy producers precise control over their Sb addition without the variability of lower-purity antimony sources.
Beyond lead alloying, antimony trioxide (Sb₂O₃) — produced from pure antimony — is one of the most widely used flame retardant synergists in plastics and textiles. High-purity antimony is also used in semiconductor applications (InSb), infrared detectors, and as a dopant in lead-acid battery grid pastes. Our 4N grade supply is spectrometrically verified with CoA supplied per batch.
Note: Available in ingots, lumps, or broken form depending on buyer preference and end application. Confirm form factor and packaging requirement when enquiring.
