Hi Rich,
The tensile strengths of 63/37, 90/10 and 95/5 solder alloys are highly
temperature and strain-rate dependent. I have a graph of tensile strengths of
near-eutectic Sn/Pb, but not the others. Bet generally, 90/10 and 95/5 solders will
be stronger than near-eutectic alloys.
Wht do you need this info--the strength of properly attached solder joints is
more than adequate for any strss-producing loading condition--other things
will fail first. This may change with LF-solders.

Regards,
