Picked up what I thought was three small bars of lead at the local gunshow this morning. Didn't really look that them. Two are marked CERROLOW-136 ALLOY. I did the web search on this stuff, pricey, but does it have any use in our hobby?

Eutectic Alloy
Contains the following metals - Bismuth, Lead, Tin, and Indium
Melting Temperature 136ºF or 57.8º C
Density .31 lbs./In3 8.8 g/cc
Initially expands then shrinks to .0000" in one hour, stable in 5 hours at -.0002" per inch.
Alloy is used in anchoring parts for machining (turbine blades, jet blades); testing, inspection, block lenses in optical manufacturing, proof casting; fusible element in safety devices (sprinkler heads); fusible cores in compound cores; low temperature solder; sealing adjustment screws and many craft applications.
Dunno what I'd do with it if I had it.
I don't like that it has Indium in it. Read the link.

sometimes a specialty alloy like that you can sell for quite a bit and then buy a whole lot more of alloy more commonly used for casting bullets. but finding the proper customer would most like involve fleabay or another online website
