For heat conduction, aluminum has a k value (heat conduction) of 250 W/m*K whereas copper has a k value of 400W/m*K so copper is almost twice as good as aluminum.

Did you contact a local machine shop? Tell them your interested in copper 110. They might not have it in stock but I bet they can get it pretty easy. Most shops always have some aluminum 6061 in stock if you go in that direction.
