Pure Copper Bare Wire — Solid Round Coil for Electrical, Grounding & Craft Use

When a project demands reliable conductivity and a clean, uncoated surface, finding bare copper wire in the exact diameter you need shouldn't be a guessing game. Whether you're a hobbyist wiring a custom circuit, an electrician running a grounding conductor, or a jewelry maker shaping intricate forms, this solid round bare copper wire gives you a consistent, workable material without the guesswork.

Each coil contains 5 meters (approx. 16.4 ft) of solid bare copper wire. Available diameters range from 1mm to 2.5mm (approx. 0.039" to 0.098"), covering gauges commonly used across electrical, industrial, and decorative applications. The wire is uncoated bare copper, offering a bright, conductive surface with no insulation or plating.

Typical use cases include DIY grounding and earthing systems, bare copper wire for jewelry making and wire wrapping, custom coil winding for electronics projects, and decorative sculpture or craft wire work where a natural copper finish is desired.

⚡ Compatibility note: This is uninsulated bare copper wire. It is not suitable as a replacement for insulated electrical cable in live mains wiring. Confirm diameter and application requirements before ordering.

✅ Key Features of These Pure Copper Bare Wire Coils

  • Solid round construction — Single-strand solid wire maintains its shape under bending, making it suitable for coil winding, forming, and structural craft applications.
  • Uncoated bare copper surface — No enamel, insulation, or plating. The exposed copper surface delivers direct electrical contact and accepts soldering without stripping.
  • Wide diameter range — Available from 1mm to 2.5mm in increments, letting you match the wire gauge to your specific current-carrying or forming requirements.
  • 5-meter coil format — Each unit is a 5m coil (approx. 16.4 ft). Multiple quantity options (1×, 2×, 3×, 5×, 10× coils) let you order exactly the length you need.
  • Natural copper conductivity — Copper's inherent low resistivity makes this wire effective for grounding conductors, earthing straps, and low-voltage electrical connections.
  • Workable and formable — Solid copper at these diameters can be bent, coiled, and shaped by hand or with basic tools, making it practical for jewelry, sculpture, and prototyping.

❓ Frequently Asked Questions

Which diameter should I choose for grounding or earthing applications?

For most DIY grounding and earthing setups, 1.5mm–2mm diameter solid copper wire is a common starting point. Larger diameters (2.3mm–2.5mm) carry more current and are better suited to heavier-duty bonding applications. Always verify the required conductor cross-section against your local electrical code before installation.

Is this wire suitable for jewelry making and wire wrapping?

Yes. Solid bare copper wire in the 1mm–1.6mm range is widely used for wire wrapping, coiling, and forming jewelry components. The uncoated surface takes patina treatments well and can be polished or left to develop a natural aged finish. Thinner diameters (1mm–1.2mm) are easier to manipulate by hand for intricate work.

Will bare copper wire corrode or oxidize over time?

Bare copper naturally oxidizes when exposed to air and moisture, developing a darkened or greenish patina over time. For electrical connections, this surface oxidation can increase contact resistance — applying an anti-oxidant compound or using sealed connectors helps maintain conductivity. For decorative use, oxidation is often a desired aesthetic effect.

Can I solder this wire directly without stripping?

Yes. Because the wire is uncoated bare copper with no enamel or insulation, it can be soldered directly without any stripping step. Clean the surface lightly with fine abrasive or flux before soldering to remove any surface oxidation for a reliable joint.

How do I choose between ordering 1 coil vs. multiple coils?

Each coil is 5 meters. If your project requires more than 5m of a single diameter, select the corresponding quantity (e.g., Qty 3 = 15m total). Ordering in larger quantities typically reduces the per-meter cost. Check the variant pricing to compare the per-coil rate across quantity options.

Is this wire compatible with standard electrical terminals and connectors?

Solid bare copper wire at these diameters is compatible with many standard crimp terminals, ring terminals, and binding posts designed for the corresponding wire gauge. Confirm the terminal's accepted wire diameter or AWG range against your chosen variant before purchasing. For reference: 1mm ≈ 18 AWG, 1.5mm ≈ 15 AWG, 2mm ≈ 12 AWG, 2.5mm ≈ 10 AWG (approximate conversions).

Can this wire be used for coil winding in electronics projects?

Solid bare copper wire is used for hand-wound inductors, transformer coils, and RF coils in hobbyist electronics. Note that bare wire coils will have turn-to-turn contact unless a separator or former is used — for applications requiring insulated windings, enameled (magnet) wire is the appropriate choice. For single-layer or spaced-winding coils, bare copper works well.
