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,
