The outer conductor/shield is encased in a PVC jacket.

Why does security alarm systems use cables with one conductor Aluminum and one Copper?
Both conductors are copper. One is just electroplated so it looks silver. This is so you can know which conductor is which when you hook them up. The copper-colored conductor is traditionally used as the positive, or plus wire. The silver-colored wire is used for the negative or minus wire. Some cables use a foil shield. The shield is mylar (polyester) coated with aluminum. The shield is not really one of the conductors, it is only used to drain away interfering signals before they reach the inner conductors, so it need not be a super good conductor. Aluminum is used for the foil shield partly because it is lightweight, but mostly because it's much cheaper than copper.
