Product Description

1kg roll of enameled copper wire (magnet wire) with polyurethane insulation, engineered for precise, high-speed coil winding in electromagnets, motors, transformers, relays, and inductors. The included spool is ready to wind, with thoughtful shaft hole sizing and end-to-end compatibility to streamline your winding workflow.

What you get: 1 roll, 1 kg. If you purchase more than one item, add to cart and checkout together to receive the calculated preferential price. For multi‑quantity orders, shipments may be split into multiple parcels.
Diameter options: Available in a range of bare copper diameters, including 0.04, 0.05, 0.06, 0.08, 0.1, 0.15, 0.2, 0.25, 0.31, 1.0, 1.3, 1.4, and 1.5 mm. Note: the listed diameter refers to the bare copper wire; the outer diameter measured with enamel is slightly larger due to insulation.
Customizable specs: The catalog covers many standard sizes, and additional specifications can be customized on request. If you need other diameters or winding attributes, please contact us.
Spool and handling: The product includes a spool. Copper wire with 1.3 mm and above can be relatively thick and may resist straightening after winding. The shaft holes at both ends are the same size for ease of use. When winding thinner wire, place the bobbin upright to let the wire fall naturally during winding.
Insulation and welding performance: The enamel coating uses polyurethane insulation, which offers excellent direct weldability up to 360–400°C. This reduces peeling during winding and speeds setup, giving you cleaner terminations and reliable connections under high-temperature conditions.
Electrical and mechanical properties: Low dielectric loss tangent, contributing to a strong Q factor at high frequencies. The wire resists pinholes during bending and stretching, making it suitable for high-speed, precision winding. It also shows good solvent resistance to common solvents and hardeners used in manufacturing.
Applications: Widely used for high-frequency transformers, inductance coils, relays, motors, and electrical instrument coils. Designed for long-term operation with a maximum working temperature below 155°C.
Standards and labeling: The wire follows UEW (Japanese standard) conventions, with QA representing national/international standards. The size designations reflect these standards, and the relationship between them is noted: 2uew = qa-1, 1uew = Qa-2. The series code (qa-1) uses the first pinyin letter of the paint, with A indicating polyurethane insulation, and -1 indicating thin film (with -2 for thick film and -3 for thicker film).

If you’re exploring options beyond the listed specifications, or need a different enamel type or color for your project, contact us. We’re ready to help you select the exact coil-winding wire that matches your design, whether you’re building a compact sensor, a high-frequency transformer, or a robust motor winding.
