(wasn't sure correct forum. moderator, feel free to move this thread.)
i'm melting tin for casting small hardware. The hardware will be tightened down with nuts and bolts, and mustn't be malleable or brittle.
Is there any DIY way to harden it? Tempering, nitriding, etc...
Going to try alloying with Bismuth and Silver. Supposedly hard recipe i found is 57%Bi/42%Sn/1%Ag
Feel free to suggest other metals. 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!
