Whether you're a hobbyist wiring a custom circuit, an electrician running a grounding conductor, or a craftsperson shaping decorative coils, this bare copper wire solid round coil gives you the precise gauge and quantity to match the job — no excess, no shortage.\u003c\/p\u003e\n    \u003cp\u003eEach coil is drawn from solid, uncoated copper with a circular cross-section. Diameters range from 0.2 mm (~0.008 in) up to 0.6 mm (~0.024 in), and quantity options run from 1 × 10 m up to 100 × 10 m (1,000 m total), letting you order exactly what the project demands.
