High quality Nichrome80 resistance wire by Twisted Messes 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 (32-44g) the resistance is much higher than you’d expect.
The 20-26g is used for single strand coils while the 27-28g is 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. The thinner gauges (32-44g) are for Clapton coils, multi-strand twisting or to add a bit of colour to your coil-art.
