Bare Copper Wire – 0.56 mm Diameter (24 SWG), 250 g Reel

This Bare Copper Wire is supplied on a 250 g reel and manufactured to a 0.56 mm diameter, equivalent to 24 SWG (Standard Wire Gauge). Lightweight, flexible, and exceptionally conductive, it is ideal for fine electrical work, school circuit experiments, and coil‑winding applications. The bare copper surface ensures excellent electrical contact when used with crocodile clips, binding posts, and circuit terminals.

Easy to unwind and shape, this wire is perfect for a variety of physics and electronics practicals in busy classroom environments.
