Specifically 70-30 cupronickel. Any links or advice on machining and/or brazing this stuff? Ususlly used in marine (salt water) plumbing and heat exchangers.

Sometimes called Monel? I've used cupronickel brazing rod, but that'd be welding rod in this case; it must be possible to weld, I've seen Monel sinks that were obviously weld-ups.
I've seen a number of marine heat exchangers, said to be cupronickel, that had the end plates soldered on but I am not sure whether it was lead-tin solder or silver solder, but I did visit a shop that was making them and the assembly was being done with an acetylene torch.

Go look for Keith Fenner on You Tube or Facebook. He can likely tell you all you would need to know.
