Copper Wire Round Solid Bare Uncoated Round 1mm 1.2mm 1.4mm 1.5mm 1.6mm 1.8mm

For delicate wire wrapping around beads and pendants, 1mm–1.2mm is the most common choice — it bends easily by hand while holding its shape. For structural frames or bangles that need to hold their form under wear, 1.5mm–1.8mm provides more rigidity. If you're unsure, start with 1.2mm as a versatile mid-point.

Solid copper wire in the 1–1.8mm range is suitable for light structural uses such as craft armatures, model frameworks, and coil winding. It is not rated for load-bearing construction or high-tension applications. For electrical grounding, verify that the diameter meets your local code's ampacity requirements for the intended circuit.

Bare copper naturally oxidises when exposed to air and moisture, developing a darker patina over time. This is normal and does not affect conductivity for most applications. For jewelry use, a clear lacquer or resin coating applied after shaping will slow tarnishing. For electrical use, connections should be properly terminated to minimise exposed surface area.

Yes. Because the surface is bare and uncoated, it accepts solder directly without stripping. Use a standard rosin-core or lead-free solder with an appropriate flux for copper. The wire can also be annealed (softened by heating and quenching) to make it more pliable for intricate bending work.

The 5-meter option is a cut length — ideal for sampling a diameter, small one-off projects, or when you only need a short run. The 1 kg option is a bulk coil of the same wire, suited for ongoing production, repeated projects, or when you want to minimise per-meter cost. Both options are available across all six diameter sizes.

For low-current DIY repairs and grounding connections, 1.5mm–1.8mm solid copper is a common choice, roughly equivalent to 14–16 AWG. Always cross-reference the wire diameter against your local electrical code's current-carrying capacity (ampacity) table for the specific application. When in doubt, consult a licensed electrician before use in mains-connected circuits.

Yes. Bare copper anneals readily — heat the wire to a dull red glow with a torch, then quench in water or allow to air-cool. Annealing relieves work-hardening from the drawing process, making the wire noticeably more pliable for tight bends and intricate wrapping. Re-anneal as needed during extended shaping sessions.
