Hard Lead Mini Ingots – 15 lb
Approximately 2–4% Antimony / Balance Lead | ~10–13 BHN | Made in USA
Rock Shot Products Hard Lead Mini Ingots provide a convenient source of antimonial lead alloy for bullet casting, alloy blending, fishing weights, and general metal casting applications.
This alloy contains approximately 2–4% antimony with the balance lead. The added antimony increases hardness compared with pure lead, producing a practical casting alloy with an approximate hardness range of 10–13 Brinell (BHN), depending on composition.
Each order contains 15 pounds of Hard Lead Mini Ingots in a mix of approximately 1 lb and 1/2 lb pieces. The smaller ingot format makes the alloy easier to handle, weigh, portion, store, and add gradually to a casting pot or furnace.
The 15 lb package provides a practical quantity for general casting and alloy-blending projects while retaining the convenience of smaller individual ingots.

Why Antimonial Lead?
Adding antimony to lead increases its hardness and resistance to deformation compared with pure lead.
With approximately 2–4% antimony, this alloy provides a useful middle ground for casters who need harder lead without moving to much higher-antimony alloys such as Linotype or Foundry-type metal.
It can be used directly when its composition is appropriate for the application or blended with other lead alloys to adjust the composition and hardness of a custom mixture.
Convenient Mini Ingot Format
Large bulk ingots can be cumbersome when only a measured amount of alloy is needed.
Rock Shot Products Hard Lead Minis are supplied in a mix of approximately 1 lb and 1/2 lb ingots, allowing individual pieces to be weighed and added gradually to a melt.
This makes storage, weighing, portioning, alloy blending, and melt-pot adjustments easier without having to cut or break apart oversized ingots.
Convenient 15 lb Package
The 15 lb package provides a useful quantity for general casting and alloy-blending projects while remaining easy to store and handle.
For customers requiring larger quantities, Rock Shot Products also offers larger package sizes and can supply material for clubs, businesses, casting operations, and other high-volume users. Contact us for volume pricing and availability.
