I need a low-toxicity, low-melting point metal (before casting), to cast hardware parts.
After casting, the parts must not crack under torque or impact, and should remain hard up to at least 100 deg C.
My plan is to make a Tin/Bismuth alloy, since low-toxicity, low-melting point.
I've heard a tiny amount of silver can make this alloy less brittle.
Any suggestions? Could be a different alloy, or a hardening process. I'm not committed to tin, bismuth, or silver. But need to keep things relatively low-toxic and low-temp. (home, indoor fab). Need to minimize shrinkage/expansion of cast part.
thx!
