Hobbyists, electricians, jewelers, and makers who work with grounding runs, wire-wrapping, or custom coil winding all face the same problem: most wire comes pre-insulated or in limited gauges. This pure bare copper wire is stocked in 24 diameters from 0.2mm to 6mm (approximately AWG 32 down to AWG 2) and in three cut lengths — 1M, 5M, and 10M — so you can order exactly what the job calls for.\u003c\/p\u003e\n    \u003cp\u003eEach spool or cut length is solid round copper wire, uncoated and unplated, with a bright bare finish. Diameters range from 0.2mm (~0.008 in) up to 6mm (~0.236 in). Thinner gauges (0.2mm–1mm) are flexible enough for intricate wire-wrapping and jewelry forming, while mid-range gauges (1.2mm–3mm) suit craft armatures, bonsai training wire, and antenna elements. Heavier gauges (3.5mm–6mm) are suited to grounding conductors, bus bars, and structural electrical work.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include DIY grounding and earthing runs where bare copper is a code requirement, handmade jewelry and wire-sculpting where the natural copper tone is part of the aesthetic, and electronics prototyping such as winding custom inductors or transformer coils. The uncoated surface also makes this wire a practical choice for scientific and educational demonstrations of electrical conductivity.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e⚡\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility note:\u003c\/strong\u003e This is uninsulated bare copper wire.

Because the surface is bare copper with no coating or plating to burn off, it accepts solder readily with standard rosin-core or no-clean flux solder.
