Has anyone used salt for freezing point depression with a copper chiller? I'm wondering what the long term effects on the internal or external surfaces may be.

Copper is pretty immune to saltwater. I don't believe it would be a problem at all, especially considering the short contact time.
Never underestimate the potential of someone who refuses to act their age.

It won't hurt it. We put little tubes of copper in the sea strainers of the boat's air conditioning systems to keep the barnacle growth down inside the cooling coils of the condensing units. And the best saltwater bottom paint is made with copper dust. Copper and problem.

The salt will wreck the copper. It kills lots of parasite in saltwater environments hence the use in systems described above. You will get a lot of patina on the surfaces and eventual failure if you use it enough. However unless you brew multiple times a week you probably won't see it fail for a few years, but it will fail sooner than with just water.
