Re: Avalon.....dooohh



But at lowish frequencies (10's of kHz), the skin depth is huge compared to
any reasonable sized conductor, so you've just got the 60% increase in bulk
resistance effect.  Al oxides are good insulators, so you don't have the
problem you do with Titanium (for instance) where the oxide is a
semiconductor.

In fact, the increased skin losses for higher frequencies might have a
beneficial effect in reducing HF emissions, much like using NiCr in a tube
amplifier plate circuit to suppress VHF parasitics.
