The reason behind that Myth is that many observe
for themselves how Aluminum will
disipate
heat faster than Copper when they remove some
Aluminum foil from the oven.
(it's not just the thin layer)
However, the key is that Copper will
transfer heat
faster than Aluminum.
If you have an all Aluminum Heatsink,
that's great!
Once your system is turned off, and the heatsource is removed,
it will cool faster than than your friend's all Copper heatsink
of the same weight.
But in an
active state, as when the CPU is operating,
Copper reigns supreme.And since Aluminum is lighter than Copper by volume
your friend's heatsink would have to be much bigger.
AMDmb.com has an excellent article about heat tranfer
if anyone is interested.

The reason that Swiftech makes the pins from Aluminum
is likely for cost and weight concerns.
