Description

Overview

Enamelled (magnet) copper wire, also known as winding wire, supplied on a 1kg spool. The conductor is bare copper with a thin polyurethane enamel layer, so it can be soldered directly without stripping the insulation first. QA-1-155 grade is equivalent to 2UEW.

Specifications

  • Net weight: 1kg per roll (packed weight approx. 1.15kg)
  • Spool package size: 14 × 9 × 8 cm
  • Insulation grade: QA-1-155 (equivalent to 2UEW), polyurethane enamel
  • Maximum continuous working temperature: 155°C
  • Direct solderability: 360–400°C
  • Available diameters: 0.04 / 0.05 / 0.06 / 0.07 / 0.08 / 0.09 / 0.1 / 0.13 / 0.16 / 0.2 / 0.25 / 0.31 / 0.4 / 0.5 / 0.65 / 0.8 / 1.0 / 1.3 / 1.4 / 1.5 mm
  • Available colours: copper / red

Purpose

Winding wire is the raw material for making electromagnets and coils. The polyurethane enamel insulates adjacent turns from each other so the coil conducts along the wire rather than shorting turn-to-turn, while still allowing the ends to be soldered directly.

Applications

  • High-frequency transformers and switch-mode power supplies
  • Inductors and choke coils
  • Relays and contactor coils
  • Electric motors and generators
  • Instrument and meter coils, voice coils
  • Electromagnet and DIY winding projects

How to Use

  1. Choose the diameter from your turns count and current requirement — note that 1kg of a thin gauge contains far more length than 1kg of a thick gauge.
  2. Keep the spool upright so the wire falls off naturally while winding; this avoids kinks and twisting.
  3. Wind with even tension and keep the turns side by side — crossed turns reduce the usable winding window.
  4. To terminate, solder the wire end directly at 360–400°C; the enamel breaks down and the joint forms without mechanical stripping.
  5. Keep the finished coil below 155°C in continuous operation.

Note: the nominal diameter refers to the bare copper conductor, excluding the enamel coating. A calliper measures the outer diameter including varnish, so it will read slightly larger than the nominal size. Wire of 1.3mm and above is stiff and cannot be straightened once it has taken a set.
