Wire-wrapping is where you have square-type connecting posts and a wire is wrapped around them. The square edges bite into the surface of the connecting wire forming an air-tight seal without the use of solder.

When alumminium is used in a cable it acts as an electrostatic shield. When you have a copper co-axial shield it acts as an RFI shield. Some cables have one or the other, or sometimes both.
