Hello,
I have a question regarding nickel strips. Bought strips from 2 different sellers, one is 0.15*28mm (5Meters) and the other one is 0.2*30mm (10m) - all two supposedly 99.7% nickel.
Color and finish looks identical. Both passed the salt water test, so it ain't plated steel. Yet the 0.2mm strip feels actually a lot more ductile than the 0.15mm. How could that be possible ? Are there other fake nickel alloys around ? How to identify which metal those strips are made of ? I measured the resistance of a piece of each strip cut to the same length, and get 2.5Ω for 0.15*28mm and 1.5Ω for 0.2*30mm.
Alternatively, could it be that the 0.2mm strip has just been processed differently to make it easier to work with ? I asked the vendors and both claim is just press-rolled.
