I use as filler for copper to stainless (or copper-copper or stainless-stainless), depending on the situation:
stainless filler
solid copper electrical wire (stripped). Flux optional.
silicon bronze brazing rod (melts just below copper, won't get runny). Don't forget the flux. Useful for when you can't get parts too hot or else they would warp, like near a short weld on ferrule (especially one that doesn't fit perfectly and you need lots of filler).
phos copper brazing rod (melts way below copper, will get runny). Don't forget the flux. Useful for binding tight joints together or where you have thin copper sheet or tubing like in a shotgun liebig.
Really, you can stick anything in there as long as it'll stick. I could MIG the stuff together with stainless wire or even mild steel if I wouldn't mind it rusting.
