    The copper heat sinks that are plated with nickel will be very heavy..a good clue for you to check it.
    Where are these found? Computers? Servers? elsewhere?

    I've been getting a lot of them in Dell P4 era computers. At first glance they look sort of like extruded aluminum, but tend to be a little shinier and the bottoms are a little thicker and definately more dense. The plating can be pretty thick so take a thick screwdriver or something and really scratch the bottom good. Go deep enough and you'll see that nice copper pink show through.

    Often it is aluminum fin soddered to a plated copper base.
