Copper will be far easier to solder... clean it well, use the right flux and enough heat.
Even w/ that special aluminum rod that they sell at swap meets, I didn't have good luck w/ Aluminum.
The guys that sell it, make it look so easy.

I've always viewed Aluminum as just an unfriendly all around metal, that doesn't play well w/ others.

Zn, Sn, Ag, Pb and Ni, are much friendlier.
