I really doubt if dissimilar metal make a difference.  My experiments all 
use aluminum-aluminum!  I have nevr used dissimilar metals in my DC work 
to avoid just such a suggestion.  A really good experiment to prove a 
point should cover most objections from observers who would question the 
results based on other principles.
