Two test methods: Pure nickel or fake nickel plated steel strip for spot welding.

I always check using a Dremel with cutting wheels. Sparks = steel .no sparks = nickel

If it were stainless steel, it is not corroded in a saline solution, even scratching the strip. To check if it is a ferric material, adding concentrated vinegar (which is used in cleaning) + diluted hydrogen peroxide (which it is sold in pharmacy) and heating without boiling, the solution should take a red-fare color, for the formation of iron acetate, soluble in water.

I just test with my spot welder. If it sparks, i got ripped off.

Easiest is to cut a 5mm long piece off then put it in a shotglass of muriactic acid plus hydrogen peroxide 3% strength. 10 parts peroxide to 1 part of muriatic acid . Then wait. If the strip is pure nickel you will have an emerald green solution, if steel it will be a brownish orange.❤

It is simple, And pure nickel will not stick to a magnet.

Well done.
