canadian ones will work if they are all copper,  find a releiivly old one, like before 1984, and chop it in half to see if its copper the whole way threw

yeah, even with american pennies they have to be from before 1984, cos since then they're 97.5% Zinc and 2.5% copper. It may be in the guide, I haven't checked...

Why not use a dew(or other soda) can and bend it into a lot of lil fins? I'll try some ascii art here...

and weld the two flat ends to the a copper plate?

Or

and again weld those flat parts to the copper?

welding aluminum, especially very small bits of aluminium, isnt easy.. actually.. its really hard and requires special tools.

you can get premade passive heatsink for pretty cheap (cut up an old northbridge heatsink or a really old processor heatsink) which will outperform a stack of pennies or a welded up aluminum can

EDIT: I just realized I said the same thing a few posts up.. but it still holds true.

Soldering is quite different from welding.. soldering the solder is what is melted and used to interface between the materials, welding you actually fuse the materials together

If you have access to a spot welder, then that's your best bet. It would obliterate your aluminum cans, just fuse little circles of aluminum to the copper base. You can also pick up thin sheets of hobby metal at hardware stores (copper, aluminum, brass, the works). It's good for tailoring your own faceplates or heatsinks.  :)
