IIRC a sacrificial metal will help in proportion to its relative position on the scale of activity. Copper is relatively inert, so anything higher (magnesium and aluminum best in that order) will work. There are more active metals (lithium, barium, potassium, sodium, calcium) but they react violently with water.

What does the 3-5 degree colder salt ice water do over non-corrosive plain ice water?  Did your experiments include Water Wetter or any of the equivalent non-corrosive products?  50/50 antifreeze?  Just thoughts... It is always better to keep it simple, even if the supply of salt seems unlimited....  cool

Stainless,
  Ya got me there. My testing showed no appricable gain with the brine solution.
But, since Salt gets everywhere, well....
  It'll look much nicer inside the SS box, anyway.
