The binary eutectic of Pb/Bi is 44.5% Pb/ 55.5% Bi (by mass)
and melts at 124 C.

Pb/Bi/Sn ternary eutectic (32.0/52.5/15.5) melts at 95 C.

There are lower melting point mixtures with cadmium,
(Wood's metal, for example, mp 70 C), but cadmium's
high vapor pressure would, I think, rule it out.

For comparison, sodium melts at 98 C;  Na/K eutectic
melts at -11 C. And Cs/K eutectic melts at -48 C
(lower than mercury.)
