Nichrome wire is used in heating coils for toasters and irons. Although it is great for those applications, it does present a fire hazard and it is considered exposed wiring since it is conductive. A draw back is that it is fragile when heated if not well supported. Just look into the top of a toaster and you will see what I mean.
