[volt-nuts] Low thermal EMF solder

[Mark Sims]

I am in the process of making some low thermal EMF cadmium-tin solder.   This material has not been manufactured in a very long time and is pretty much unobtainable these days (despite it being listed as the product of several companies in India).  It gives the safety geeks apoplectic fits at the mere mention of the first syllable of "cadmium"...

I have seen references to 60:40 solder and 70:30 Cd:Sn solder.   At one time I saw a table that showed the characteristics of a few type of Cd:Sn solders,  but have been unable to locate it.  Does anybody have any references to the properties of Cd:Sn solders?
