Electricians, jewelers, sculptors, and serious DIYers who need a dependable solid bare copper wire in a specific diameter and length will find this listing covers the full range they need — from a compact 1 m coil to a 15 m run — without having to buy more than the job requires.\u003c\/p\u003e\n    \u003cp\u003eEach piece is drawn from solid, uncoated pure copper rod, giving you a round cross-section with no hollow core. Available diameters span 3 mm (~0.118 in), 3 mm soft-temper, 3.5 mm (~0.138 in), 4 mm (~0.157 in), 4.5 mm (~0.177 in), and 5 mm (~0.197 in). Lengths run 1 m, 3 m, 5 m, 10 m, and 15 m per variant.

However, direct-burial suitability for electrical conductors depends on local code requirements — many jurisdictions require a minimum burial depth and may mandate a protective conduit or a listed direct-burial rated conductor. For purely decorative outdoor use (garden sculpture, trellises, floral wire), bare copper performs well in most climates.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eCan I solder or braze this wire without special preparation?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eYes. Because the wire is uncoated, there is no insulation to strip before soldering. Use a rosin-core or acid-core solder appropriate for copper, and apply flux if needed for a clean joint. For brazing (higher-temperature joining), standard copper-compatible brazing rods and flux work without additional surface preparation. Lightly sanding the joint area with fine-grit paper improves adhesion if the surface has developed a heavy patina.\u003c\/p\u003e\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow do I cut and bend the thicker diameters (4 mm, 4.5 mm, 5 mm)?\u003c\/summary\u003e\n      \u003cdiv class=\"hdiy-faq-body\"\u003e\u003cp\u003eFor clean cuts, use heavy-duty wire cutters or bolt croppers rated for the wire gauge — standard electrician's diagonal cutters handle up to about 4 mm; for 4.5 mm and 5 mm, bolt croppers or an angle grinder with a cutting disc give a cleaner result. For bending, a conduit bender, bench vise, or pipe bender jig prevents kinking.
