Possibly you can get acceptable results by mechanically abrading the lead,
(there are special tweezers with abrasive pads, or you could even use very
fine grit "wet and dry" ) followed by as high a solids content RMA as you
can find. The high solids will increase the flux persistence and therefore
working time before displacement by the solder on dipping.

Subject: [TN] Soldering Nickel Leads
Hey all,
I have a minor problem with a component in house. The component leads
are 19 AWG nickel and I need to connect to them using 20AWG copper wire.
I looked in the archives for previous discussions on this topics and
came away with the impression that OA flux is required. My question is:
Can I solder these parts without having to go out and get some OA flux?
We use RMA and I'm reluctant to bring in a different flux and have it
used rather than the RMA. Can one mechanically prep the leads, then
flux with RMA, then dunk in the solder pot?
Thanks in advance for all your input!
