Appears that you are talking about soldering metals to metals and not
soldering to electrical components. If this is true, mechanical
soldering requirements and not J-STD-001 soldering would normally apply.
Is this a soldering or otherwise a brazing operation since many heat
sinks are brazed to the copper pipes using dip braze or furnace brazed
process rather than soldered.

Usually a sacrificial gold is the final finish over the nickel. The
fluxes used to solder to nickel are unique. IMHO, no-cleans; not
allowed.

In my experience nickel is NOT easy to solder to at all.

Fellow TechNetters:
Should I be concern with an electroless matted nickel plating over an
aluminum sheet metal surface and solder onto a copper heat tube? I
recall something about directly soldering onto a nickel surface. Beside
nickel oxidation. Any suggestions would be greatly appreciated.
Victor,
