It's not a problem.  If you properly solder copper wire to standard EOL
resistors there will be no degradation at all.

They're not made of aluminum.

No, Phil, it does NOT happen if you properly connect them, even in if you
think it will in your 40 weeks in the trade.  :^)

Commonly used EOL resistors do not cause problems when placed in contact
with copper.  BTW, I don't claim 40 years in the trade -- only 28.
