I don't understand how the increased resistance of aluminum over copper
could
be frequency dependent. It makes sense that with high peak currents,
the
increased resistance could cause increased voltage drop, but that can be
compensated for by using a larger ocnductor. I know that airplanes,
which are
made of aluminum, carry some pretty large currents through the skin
during a
lightning strike, and they are also the source of the ground for the
onboard
radars and radios operating both above and below the frequencies
suggested
here for tesla coils - can you elaborate on this frequency dependency of
aluminum???

Not a good idea to use aluminum. The Tesla secondary requires a very,
very
good ground. Aluminum is not a good conductor (relative to copper) at
the
high frequencies employed by Tesla oscillators. I know it costs more
but
consider the effect a less effective ground may have on your secondary
coil
-- like burning it up! Save your aluminum buss for the 60 HZ currents.
Consider copper again unless you are on a very very tight budget and
never
use aluminum for a primary.
