I have never heard of aluminum braided or spiral-wrapped cable shielding an=
d I think the reports of it above may be based on misunderstanding of cable=
 specifications. It would not be solderable, nor would it make a reliable c=
rimp connection as aluminum oxide is a good insulator. Cables for installat=
ion are made with aluminum foil shielding which gives 100% coverage. They h=
ave a tinned copper drain wire for connections, as aluminum can't be solder=
ed. Those cables are not intended for flexing; the foil shields will break =
up.
