   Copper 'work hardens' when flexed. Over time it develops cracks, then
breaks. Stranded wire uses smaller conductors and has less problems per
conductor, due to a larger bending radius VS the diameter of the
conductor.  The steel center conductor is meant for permanent
installation, but it holds up better on the bench that solid copper
coax.
