Solid Bare Copper Wire 99.9% Pure — Reliable Conductivity for Wiring, Craft & Electrical Work

When a project demands consistent conductivity and a wire that won't let you down mid-run, most hobbyists and tradespeople know the frustration of coated or alloy wire that corrodes, resists soldering, or snaps under tension. This solid bare copper wire is built for makers, electricians, jewelers, and DIYers who need a dependable, uncoated conductor they can shape, solder, and trust.

Each spool is drawn from 99.9% pure copper in a solid (non-stranded) round profile. Diameters range from 0.2 mm (approx. 0.008 in) up to 2.5 mm (approx. 0.098 in), with spool lengths of 5 or 10 meters depending on the gauge selected. The wire ships bare and uncoated — no enamel, no tinning — so the copper surface is immediately ready for soldering, forming, or grounding connections.

Typical applications include jewelry wire-wrapping and bead work, PCB repair and electronics prototyping, earthing and grounding runs in low-voltage installations, sculpture armatures, and craft projects where a workable yet firm wire is needed. The multi-pack options (1–10 spools) let you stock up on the diameter you use most without over-ordering.

⚡ Compatible with standard soldering irons, wire-wrap tools, round-nose pliers, and most jewelry-making jigs. Suitable for use in low-voltage DC grounding, craft armatures, and electronics breadboarding.

✅ Key Features of These Solid Bare Copper Wires

  • 99.9% Pure Copper — High-conductivity grade copper ensures minimal resistance loss, reliable soldering adhesion, and consistent performance across electrical and craft applications.
  • Solid Round Profile — Single-strand construction holds its shape when bent or coiled, making it easier to form precise loops, coils, and wraps compared to stranded wire.
  • Uncoated Bare Surface — No enamel or tinning means the wire is immediately solderable and bondable without stripping — ideal for grounding lugs, jewelry clasps, and PCB jumpers.
  • Wide Diameter Range (0.2 mm – 2.5 mm) — Sixteen gauge options from ultra-fine 0.2 mm (suitable for delicate bead work) to robust 2.5 mm (suitable for structural armatures and heavier grounding runs).
  • Flexible Multi-Pack Quantities — Choose 1 to 10 spools per order to match your project volume, reducing per-unit cost when buying in bulk.
  • Consistent Spool Lengths — Finer gauges (0.2 mm – 0.6 mm) come on 10-meter spools; heavier gauges (0.7 mm – 2.5 mm) come on 5-meter spools, sized to match typical usage per project.

❓ Frequently Asked Questions

Which diameter should I choose for jewelry wire-wrapping?

For delicate bead work and fine wire-wrapping, 0.2 mm – 0.4 mm is the most common range — thin enough to pass through small bead holes and wrap tightly around findings. For structural frames or heavier pendants, 0.6 mm – 1.0 mm provides more rigidity while still being hand-formable with round-nose pliers.

Is this wire suitable for grounding or earthing connections?

Yes. Bare 99.9% copper is a standard material for low-voltage DC grounding runs, chassis bonding, and earthing straps in hobby electronics and small installations. For mains-voltage or code-regulated electrical work, always verify local wiring regulations and use appropriately rated cable assemblies.

Will this wire corrode or oxidize over time?

Bare copper will develop a natural patina (surface oxidation) when exposed to air and moisture over time. For most electrical and craft uses this does not affect performance. If a bright finish is required long-term, store unused wire in a sealed bag or apply a clear lacquer after forming. For outdoor or high-humidity environments, consider tinned copper wire instead.

Can I solder directly to this wire without stripping or pre-treating it?

Yes — because the wire is uncoated, there is no enamel or insulation to remove before soldering. Standard rosin-core solder and a clean iron tip will bond directly to the bare copper surface. Lightly abrading the wire with fine sandpaper before soldering can improve adhesion if the surface has begun to oxidize.

What is the difference between solid and stranded copper wire, and which should I choose?

Solid wire is a single continuous conductor — it holds its shape when bent, making it ideal for wire-wrapping, coil winding, and fixed installations where the wire won't flex repeatedly. Stranded wire is made of many thin filaments twisted together, giving it greater flexibility and fatigue resistance for applications that involve repeated movement. For jewelry, sculpture, and static wiring runs, solid wire is the correct choice.

How do I choose between the 5-meter and 10-meter spool lengths?

Spool length is determined by diameter: finer gauges (0.2 mm – 0.6 mm) come on 10-meter spools because a small amount of wire by weight covers a longer length. Heavier gauges (0.7 mm – 2.5 mm) come on 5-meter spools. If you need more total wire, simply increase the pack quantity (up to 10 spools) rather than mixing diameters.

Is the wire compatible with standard wire-wrap tools and coiling jigs?

Yes. The round solid profile feeds smoothly through most wire-wrap pens, coiling gizmos, and mandrel jigs. Diameters up to approximately 1.0 mm are typically hand-formable; gauges above 1.2 mm may require flat-nose or chain-nose pliers for tight bends.
