what's the difference between 60/40 and 50/50 solder?

Why would you prefer 50/50 over 60/40?


I should know the answer to this. Seems to me I never used 50/50 solder
when I had my own studio but I'll be darned if I can remember why!!

Enlighten me please.

Thanks.

melting temperature and tensile strength. 60/40 is inherently easier to
flow out due to lower melting temp.
cost is slightly more though.

I always make my beginning students cut glass with a $2 cutter, and solder
with 50-50 for their first experience. When they move to a carbide super
cutter, and 60-40 solder, they can really appreciate the difference. 50-50
is lumpier, not as shiny or as easy to get a nice bead with. That said, I
know many folks that use it exclusively. Go figure?

I remember reading someplace the the different alloys also have
different "open" range. (upper/lower temperature limit where the
solder is nicely workable.)

I seem to recall that there was a third 63/37 blend that is
supposed to have a really narrow "open" time/range that is used for
sculptural solder.

I googled around to try and find the page, but couldn't. sorry.

Does this match people's experience?
