[volt-nuts] cadmium solder alloy for low thermal emf?

Getting cadmium alloy isn't as difficult as it seems. I've got an offer 
from a factory 20km away (http://www.chemet.de 
<blocked::blocked::http://www.chemet.de/>), that sells 18%-cadmium 
solder (S-Sn50Pb32Cd18 / DIN EN ISO 9453), but I have to order 1kg at a 
price of 70 Euro. Moreover, I'm not sure, if the Cd18 solder works, 
since all the sources recommend a 50% cadmium alloy.

If there are appropriate alternatives (e.g. Pb90Sn10?), I'm going to 
avoid cadmium, of course.
