My main test for every nickel strip roll I receive is to cut the strip with a dremel disc and see that it doesn't throw sparks.
I once tried a plated steel that I scratched with sand paper and put in salt water and it didn't rust (waited hours, then days, nada) and it WAS nickel plated steel, I could spot weld it super easy.
So since it didn't rust I don't trust that method.
Anyway, today I received a nickel strip from a different supplier and it DID spark when cut.
The feel of the material does feel like pure nickel (nickel feels different than steel and looks less shiny).
I tried to spot weld it and it seemed to work the same (didn't burn under the same power settings I use for pure nickel).
Is there another reliable test?
How can I test resistance in the most reliable way?
