Bare Nichrome Wire – 0.27 mm Diameter (32 SWG), 125 g Reel

This Bare Nichrome Wire is supplied on a 125 g reel and manufactured to a 0.27 mm diameter, equivalent to 32 SWG (Standard Wire Gauge). Known for its excellent heat resistance, oxidation resistance, and stable electrical properties, nichrome wire is ideal for high‑temperature and resistance‑based applications in school science laboratories. Its predictable resistance characteristics make it especially suitable for physics experiments, heating elements, and coil‑winding activities.

The bare finish ensures reliable electrical contact and easy connection to terminals, crocodile clips, and experimental setups, making it a versatile classroom resource.
