Yes but as mentioned earlier with china sellers is that just because it was pure nickel once doesn’t mean it will be again.

I’ve had good luck on ali express. Everyone that said 99% pure nickel with descriptions showing how proud of the nickel they were sent me nickel. Most of them say they’ll do custom stuff. Links from my order history:
(don’t get .25 or .3, too thick for spot welders)
(2 orders, 2 different widths)

Sigh I just bought this, then looked again and saw it’s plated. Did you scratch before brine?
Damn I wonder if they changed description and I did notice the packaging changed. I’ll have to test the new stuff. Initially I scoured with a Dremel and did brine test, to which it passed
I think it’s a language thing, “plate” of pure nickel, not “plated” in nickel. Well at least some of the time. I see listings saying things like “99.94% pure nickel plate” that turned out to be nickel, not plated steel.

Good stuff, all I know is that the description to the one linked states nickel and steel as materials.
