Can't prove it, but I believe even Alfin drums actually don't transfer heat
as well as solid iron drums do, because of the steel/aluminum interface.
The Alfin process improves the interface a good deal over just butting the
two together, but the transition still causes a bigger barrier than the
improved conduction of the aluminum can make up for.

I'm also not certain that the Datsun drums use the Alfin process.  Is anyone
else ?
