Title says it all: I'm thinking of making a snubber network with a cap and a low turn-count coil that's hard up against a ground plane, so I get series R, parallel R, and a bit of inductance all in one go.
But it's a no-go if it can't be made from easily found wire and just soldered down in production.
Suggestions?

Constantan solders easily - IIRC about 30 x resistivity of Cu.

If you don't care much about the tempco, just use brass wire. It's pretty high resistivity and easily available.
This is a good suggestion.. for small quantities, just strip some type T or J or E thermocouple wire.. AWG20 solid is quite common. The Constantan is the red (negative) wire with US color codes.

Phosphur Bronze has about 7x the resistivity of copper. You can also solder stainless with some 'nasty' fluxes. All kinda 'springy' though.

Manganin solders pretty well and has a very low tempco.

In some lab cases i brazed the ends of nichrome wire to make solderable tips. Not recommended for production.
