Lingotto di antimonio 99,65%

Sb

Antimony ingot at Sb ≥ 99.65% is a refined cast metal supplied in ~25 kg ingots for metallurgical and chemical conversion. Antimony hardens soft metals and acts as a flame-retardant synergist in halogenated systems: in lead alloys it raises strength and casting fluidity, while as a trioxide precursor it reacts with the halogen source to form antimony halides that scavenge H· and OH· radicals in the gas phase and interrupt flame propagation. Primary uses are antimony trioxide (Sb₂O₃) feedstock, lead-acid battery grid alloys, flame-retardant masterbatch chemistry, and bearing or pewter alloys. Lead-antimony grids typically run 1.5-3% Sb for cycling durability; bearing babbitts carry roughly 7-15% Sb for hardness and load capacity. The 99.65% grade with controlled residuals — As ≤ 0.10%, Fe ≤ 0.05%, Pb ≤ 0.10%, S ≤ 0.06% — keeps trioxide whiteness and battery-alloy behavior consistent by limiting elements that promote gassing or discolor the oxide. Each lot ships with COA and MTC, drawn from multi-regional sourcing into Gebze bonded stock with CIF Marmara delivery and 20 MT FCL options. Send your target grade and tonnage for an RFQ.
