I think the "R" part of this wire is NiCr
If you heat it up, it get a shiny blue colour, Kanthal dosnt do this, Kanthal is more brownish
Its not magnetic, kanthal is, cause Kanthal contain Iron
This is not a problem for me, I like NiCr and the quality of the wires is very good.
I can second that opinion, my 1.7 ohm SKU 1760909 came in. It's not magnetic (unlike Kanthal), and even the 1.7 ohm has thinner resistance wire than the NR leads. As far as I can tell, it's the same quality as the 1.7 ohm NR-R-NR from SKU 1761000, but with this you get 100 pcs vs. 50 wrapped with mediocre silica. Meh.
