Unless the wire is some exotic alloy that contains LARGE amounts of metals incompatible with anodizing (like copper and iron) no. I THINK aluminum welding wire is OK.
It would help to leave a incomplete thread on the wire (or hole) so that you force the metals to cold flow when you tighten the connection. This is easier to do with soft alloys (like 1100).
We are having a problem with semantics here; it seems that those who understand what "tight" means in the DC electrical sense have little/no trouble with connections. "DC electrical sense" means "tight" like the battery cable in your car, not "tight" like under a wire nut in 120/240 VAC wiring. It is the nature of high voltage AC to be highly tolerant of connections, this is not the case with low voltage DC. Im getting a bit frustrated, but such is life.
