IEC STANDARD 2UEW 0.3MM SELF BONDING ENAMELED COPPER WIRE MAGNET
WINDING WIRE FOR VOICE COILS
Enamelled copper wire comes in many different diameters, and with
several different kinds of enamel. The diameters vary from less
than that of a hair, to about that of a child’s finger. Different
standards exist for the wire diameter. A very common one is
American Wire Gauge, shortened to AWG, which is used in much of the
world. Britain has its own standard, and in many countries the wire
is specified simply by its diameter in millimeters.
