I'm hoping some tech-net metallurgist/alchemist or other wizardly type can help me with this.

I had a stray thought this weekend and can't seem to find the flaw in my logic.
Here is how the thought process went;
-Copper oxidizes and must be coated to maintain solderability.
-Certain copper alloy's remain solderable even after long term storage and exposure to hand oils etc. (i.e.;alloy 752)
-Why isn't a corrosion resistant alloy used in the manufacture of PCB's?

I know the electrical resistance is higher for alloy's but it seems this could be compensated for the same as trace resistance is now, just get a new set of numbers.

What am I missing, this is really driving me nuts.
