Description

Hard Lead alloy 6% tin 25% antimony

Lead alloy ingot with highantimony content.


Antimony expands during cooling after it was cast. This compensates for the shrinking of lead and grants the exact gauge of a cast projectile for guns and revolvers.
The ingots can be smashed with a hammer to obtain smaller parts for alloying.
Suitable for casting bullets, figures and leterpress types.
This very hard and brittle alloy is used toalloy withsoft lead for the casting of projectiles in molds.
Please note: It may not be used on its own for bullets. The result would be way too brittle.
