Andy,
I know this answer is outside what most would suggest, but I offer it a something that worked on usually non-solderable materials. I'm sure the chemists in the group will have their heads pop with this suggestion.
I haven't tried that but I have soldered stainless steel with 63/37 solder and La-Co Industries N-3 All Purpose flux found at McMaster-Carr as p/n 7696A1. The SDS suggests it contains zinc chloride, ammonium chloride and hydrochloric acid. I was impressed by the success of the soldering, but my application was not electronics. It must be cleaned with lots of water.
We did use it for soldering a drain wire to a stainless steel foil transformer shield that was then wound into the transformer.

Subject: [TN] Soldering to 'Nickel-Silver'
Hi Folks,
Has anyone had experience soldering to 'Nickel-Silver'
This is a ternary alloy with approximately 60% Cu, 20% Ni, 20% Zn.
If so, are there any special considerations such as flux type, pre-tinning etc...
Best Regards,
Andy
