Why arent there aluminum-copper alloy heatsinks?

The thermal conductivity of copper and the light weight/easy released aspect of aluminum could easily be balanced out. Thoughts?

Because it's an extra expense that's barely ever needed.

Gino Palma :

There are plenty of heat sinks that use aluminium fins surrounding a copper core, I believe that Intel's stock heat sinks are built with this design.

They probably only use enough copper in key areas then get by with aluminum - not only for the sake of weight but due to the price of copper.
