Nichrome 80 series resistance wire is composed of 20% Chromium and ~80% Nickel. It’s a low resistance wire under normal circumstances. When dealing with the thinner gauges of this wire (32-46g) the resistance is much higher than you’d expect.
The thinner gauges (32-46g) are for clapton coils, multi-strand twisting or to add a bit of color to your coil-art.
The 28g and 30g can be used for core wires of multi-strand claptons like Alien Claptons but the thinner gauges (32-46g) will not perform well as a standard coil So if you’ve never used high-gauge wire before, make sure you’re buying the appropriate wire for your build before purchasing.
