Hello.
I repeated the experiment with a better setup, I also added
some alloys that are already arrived. So far, a really "low"
EMF solder hasn't been identified.

Measurements have been done between water ice point and boiling
point with Agilent 34401A. I don't expect the curves be linear,
but here it's assumed they are.

Copper - Sn96.5/Ag3/Cu0.5 -> 3.35uV/K
Copper - Sn95.5/Ag3.8/Cu0.7 -> 3.22uV/K
Copper - Sn60/Pb40 -> 3.34uV/K
Copper - Pb92.5/Sn5/Ag2.5 -> 3.02uV/K

Copper - Brass -> 3.30uV/K

I am waiting for Sn96/Ag4, Sn99/Cu1.

Any plans on testing Sn42/Bi57.6/Ag0.4 ?

Thanks,
Herbert

It would also be interesting to get SN100C in the mix if you can find it...
