I'm trying to find out *for sure* wha hte alloy mix is of the
fixturing alloy sold by ENCO. They say it expands by .0002"/inch when
it solidifies and that it melts at 158°F. In the machinist's handbook
they describe an alloy that melts at 158°F made of Bismuth, tin, lead
and cadmium but they don't specify that it expands on solidification.

Anyone have some knowledge about this?

And where I can find some cadmium cheap?
