Does anyone use 100% lead-free solder? IS there such a thing?
I know that solder with relatively higher % of tin has a lower melting point than solders with more lead in them, but in my business (space/aerospace) there's a movement to get away from tin because of certain funny properties it has over time.
We used to use lead sticks (70-80% lead) as a filler on cars, some guys still do, especially on "real" classics (read: 7 or 8-figure "golden age" handbuilts.)
I guess I am wondering when "lead" becomes "solder" in the frame-builder's lexicon, or if I should be wondering more about when the nubbly campy shifters were smoothed out -smile-
