[VAC] Re: Polishing - .05 inches of Alclad ?

[wescott50@xxxxxxxxx (Bill Scott)]

The cladding on Aluminum has always been something of a mystery.  It was
on the 2024 T3, and on other aluminum used on Airstreams.  RJ, has
spoken about it and others have kicked the subject around, but we have
not had an "expert" talk about how Kaiser, or Reynods, or Alcoa applied
the cladding.  Some have said it is  several hundreds thick, and some
have said it is several thousands thick.  Is it pure aluminum?  Is it
applied by electrolisis?   Is it much more expensive?  I've heard it
referred to as alcad, and alclad.   What is it exactly, and who is the
expert that will finally shed some light on this subject.  Of the over
300 members on this list, we should have some good aviation types that
know.

Anybody????
