Roto203F Low Melt Fusible Bismuth Based, Lead, Tin Alloy Ingot

Using this alloy to cast mineral crystal at low temperatures to minimize heat damage to the mineral structure. This Alloy works great and doesn't produce any slag.

Excellent quality, great value. The quality makes it very easy to work with. Highly recommend

Easy to work with, nice castings.

In California expanding lead free projectiles are the only thing used. My dilemma was being able to harvest with my father’s .54 cap lock Rifle. I am sure this product will expand on impact, even a thousandth and the big ball will do the rest at 50 yards. Great deal allowed me to let me use with my many old guns. Curio relic are my favorite. Thanks

Using ROTO203F as a low-temp solder for chip removal, works well for that application.
