Bullet Alloy
Pb-Sb-Sn billets blended to your target hardness for ammunition manufacturing — consistent composition batch after batch, with elemental analysis on every shipment.
Bullet alloy blended to your hardness
For casters and ammunition manufacturers, consistency is everything. A bullet alloy that drifts batch to batch means changing hardness, fillout, and sizing — and constant re-tuning of your process. We blend lead-antimony-tin (Pb-Sb-Sn) alloy to a target hardness and hold that composition shipment after shipment.
Antimony adds hardness; tin improves how the metal fills the mold and helps the antimony alloy in cleanly. We dial those percentages to the Brinell hardness (BHN) your application calls for, whether you're casting plinking rounds or hard-cast for higher velocity.
Every batch is quality-checked and ships with elemental analysis, so you know the exact composition you're loading into your pot — no guesswork, no surprises.

Frequently asked questions
What is your bullet alloy made of?
A lead-antimony-tin (Pb-Sb-Sn) blend. Antimony controls hardness and tin improves casting fillout; we set the percentages to your target.
Can you match a specific hardness?
Yes. Give us a target Brinell hardness (BHN) or a reference alloy you already use, and we'll blend to match it.
What form does the alloy ship in?
Billets or ingots sized for your melting setup. Let us know your preferred form and weight.
Do shipments include analysis?
Yes — every shipment includes elemental analysis so the composition is documented and repeatable.
What quantities can you supply?
From small batches for individual casters up to production runs for manufacturers. We're based in Morris, Alabama — call 205-427-3599 or use the form below.
