Electroplated wire, most likely nickel.

Jack plugs and sockets, DC plugs etc.

I have some mil spec, high-temp wire that's nickel plated. Beautiful
stuff, strands wound in layers. It takes an unusually high temperature
and a long time before the solder wets and soaks into it. It does tin,
but I wouldn't say it solders "beautifully", not with ordinary fluxes.
