At Mayer Metals, we understand how important alloys are in the ammunition industry. We provide ammunition manufacturers with pure lead ingots, lead wire and Sn/Sb/Pb Bar for bullet and musket ball production.

4 Metals in Cast Bullet Alloys

  • Lead (Pb) is a heavy metal that helps carry a bullets momentum until it reaches the target. Lead can be heat treated to lessen brittleness and conducts heat very slowly, making it an ideal alloy for bullet making.
  • Antimony (Sb) is a metal that helps strengthen and harden bullets. It has tin-like qualities that help the alloy flow easier into the mold.
  • Tin (Sn) helps reduce dross, or minimal waste, during casting.
  • Arsenic (As) is used as a catalyst during heat treating process.

We also provide lead-free materials in states where it is required, such as California, to comply with the ban on .45 ACP ammo.

If you cast your own bullets or are an ammunition manufacturer, Mayer Metals has the supplies you need. You’ll find the highest-quality materials at great pricing.
