Purple Copper Wire Round Solid Bare Wire Diameter 0.2mm-1.7mm Wire/Cable/Brush

The correct diameter depends on the target inductance, the number of turns, and the current the coil must carry. Finer gauges (0.2–0.5 mm) suit high-turn-count inductors and transformers where space is limited. Heavier gauges (1–5 mm) are used where lower resistance and higher current capacity are needed. Cross-reference your design specification with a wire gauge current-capacity table before ordering.

Solid copper wire in the 0.5–2 mm range is commonly used for wire brush tufts in light-duty surface preparation and cleaning brushes. Copper is softer than steel, so it is suited to non-ferrous surfaces where steel bristles would cause contamination or scratching. For abrasive industrial brushes, confirm the required tensile strength against your application before selecting a diameter.

Bare copper oxidises when exposed to air and moisture, forming a patina that can increase surface resistance over time. For electrical applications where low contact resistance matters, store unused wire in a sealed bag or airtight container away from humidity. The rose gold colour coat on this wire provides a degree of surface protection, but it is not a full insulating or anti-corrosion coating.

This wire is listed as suitable for air-conditioning applications. However, any electrical repair must comply with local wiring regulations and be carried out by a qualified technician. Verify the required conductor cross-sectional area (mm²) for your specific circuit load before selecting a diameter, and ensure the wire is rated for the operating voltage of the system.

Meter packs (1 m, 2 m, 5 m, 10 m, 15 m) are cut lengths suited to small repairs, prototyping, or projects where you need a precise quantity. The 1 kg spool provides a larger continuous length whose exact meter count varies by diameter — thinner wire yields more meters per kilogram than thicker wire. The 1 kg option is more economical for production runs or repeated use of the same gauge.

Yes. The solid round cross-section and rose gold finish make finer gauges (0.2–1 mm) well suited to wire-wrapping, coiling, and forming decorative shapes. Copper is easy to work with hand tools and holds formed shapes without springback issues common in harder metals. The rose gold tone also complements warm-toned jewellery designs without requiring additional plating.

The length per kilogram depends on the wire's cross-sectional area and the density of copper (approximately 8.96 g/cm³). As a rough guide: 0.5 mm diameter wire yields roughly 570 m/kg, 1 mm wire yields roughly 140 m/kg, and 2 mm wire yields roughly 35 m/kg. For precise calculations, use the formula: Length (m) = 1000 g ÷ (π × (d/2)² × 8.96), where d is diameter in mm.
