For stainlesss and aluminum it is aobut 0.25 - 0.40, depending on the aluminum composition. In the real world, for this non-critical installation, it's not a big deal, but I would probably still pay a few bucks more and get the sst myself. The other option is to go with a factory painted rivet which prevents the metals from coming in direct contact (I know you can buy white ones).
i only use gold rivets

0.00 anodic index baby!
