Pure Copper Wire Solid Bare Round 0.2mm - 5.5mm Jewelry Making Craft Uncoated

For wrapping cabochons and beads, 0.4–0.8 mm (approximately 26–20 AWG equivalent) is the most common range — fine enough to weave through bead holes yet stiff enough to hold a wrapped frame. For structural bail or frame work, 1.0–1.5 mm gives more rigidity. Thicker gauges (2.0 mm and above) are better suited to bangles, cuffs, and sculptural elements that need to hold their shape under wear.

Finer gauges (0.2–1.0 mm) can typically be bent, coiled, and shaped by hand. From 1.2 mm upward, round-nose or flat-nose pliers are recommended to achieve clean bends without work-hardening the wire prematurely. Gauges 3.0 mm and above generally require heavier-duty pliers or a bench vise for tight bends.

Yes — uncoated copper naturally develops a patina when exposed to air and moisture, shifting from bright reddish-orange toward darker brown or green over time. Many jewelers and craft makers intentionally accelerate this with liver of sulfur or salt-and-ammonia patination. If you want to preserve the bright finish, apply a clear lacquer or jewelry sealant after forming. The wire itself does not corrode structurally under normal indoor conditions.

Yes. Because the wire is bare and uncoated, it accepts standard rosin-core solder without any stripping or pre-treatment. Use a suitable flux for the gauge — thicker wire (3 mm+) requires more heat dwell time to reach soldering temperature. For jewelry applications, silver-bearing solder or copper-compatible hard solder can be used with a torch.

Gauges from 0.2 mm to approximately 1.5 mm are compatible with most plastic and metal wire jigs (such as Wig Jig or Coiling Gizmo-style tools). Thicker gauges may require a mandrel or round-bar form rather than a peg-style jig. Always check the maximum wire gauge rating of your specific tool before use.

For electronics coil winding (inductors, transformers, electromagnets), the gauge is determined by the required current capacity and the number of turns that must fit in the coil former. Thinner wire (0.2–0.5 mm) allows more turns in a given space but carries less current. Thicker wire (1.0 mm+) carries more current but requires a larger former. Consult your coil design specifications for the correct AWG or metric diameter before ordering.

Each unit is cut to 1 meter (approximately 39.4 inches). A small cutting tolerance of ±1–2 cm is typical for hand-cut wire lengths. If your project requires a precise length, plan to trim to final dimension after receiving. For bulk or precision-length requirements, contact us to confirm options.
