Nichrome is a nickel-chromium alloy wire. It will not work with any TC mods out there (to my knowledge.) It's resistivity is lower than kanthal A1 but higher than SS.
Lots of people like it for things like alien claptons and fused claptons because it heats up a bit quicker than kanthal and turns pretty colors, but you can build anything with it. You can use it for anything that you would usually do with kanthal. You can typically squeeze in an extra wrap or two vs kanthal without going too high up in resistance or having too slow of ramp up.
It's worth noting that just like with plain nickel wire, some people have problems with nichrome causing irritation. Most people have no reaction to it, but it can happen. Some people also don't like the taste, while others swear it's cleaner than kanthal.
