I can get a goodly readable contact potential between copper plate, and nickel particles in a rubber matrix, let alone between to clean pieces of metal, although, yes, a salt bridge would help even moreso :-)
I recommend tomato ketchup/catsup as a contact electrolyte. Or katsu or teriyaki sauces.

The presence of less than ten percent alloying ingredients that in no way alter the crystal structure of the alloy is negligible.
