Bare Copper Wire – 0.45 mm Diameter (26 SWG), 250 g Reel

This Bare Copper Wire is supplied on a 250 g reel and manufactured to a 0.45 mm diameter, equivalent to 26 SWG (Standard Wire Gauge). Lightweight, flexible, and highly conductive, it is perfect for fine electrical work, precision coil winding, and detailed circuit construction in school laboratories. The bare copper surface provides excellent electrical contact, making it ideal for use with crocodile clips, binding posts, and other circuit components.

Easy to shape and unwind, this wire supports a wide range of physics and electronics experiments, particularly where thin, responsive conductors are required.
