Enamelled Wire
Magnet wire in copper or aluminium with enamel or polyurethane insulation.
Enamelled wire, also known as magnet wire or winding wire, made by coating a thin insulation layer of enamel or polyurethane over a copper or aluminium conductor. Flat conductor thickness runs from 0.8 to 5.6 mm and width from 2.00 to 16.00 mm at a 1.4:1 width ratio, with 130 polyester enamelled wire among the categories supplied. Conductors are available solid or stranded.

The problem
What This Group Is Built To Solve
Insulation thermal class is the number that sets a transformer's or a motor's permitted operating temperature, and it is the number most often left off an enquiry. Specifying wire by diameter alone means the thermal class arrives as whatever the supplier had, and the design temperature is then set by accident.
Who buys these
Who This Range Is For
Transformer Manufacturers
Enamelled wire is the winding material in every wound transformer, and its thermal class sets the design temperature.
Motor Manufacturers and Rewinders
Magnet wire in copper or aluminium is the basic input for motor winding and rewinding.
Coil and Inductor Makers
Flat wire at a 1.4:1 width ratio is what fills a coil window efficiently, which round wire of the same section cannot.
Why these
What Makes This Range Different
Insulation That Fits Between Turns
A thin enamel coating insulates without taking winding space. That is the whole reason magnet wire exists instead of insulated cable.
Flat and Round Conductors
Flat wire packs more conductor into the same coil window. Both are made, so the coil design decides rather than the supplier's stock.
Copper or Aluminium Core
Copper for conductivity, aluminium for weight and cost, both selected for their conductivity properties.
Thermal Class Stated
130 polyester enamelled wire is a defined thermal class, which is what allows a design temperature to be chosen deliberately.

63% IACS against 99% IACS. With both figures published, the choice between aluminium and copper foil becomes arithmetic at design stage rather than a matter of preference.
FAQ
Enamelled Wire Questions
What is enamelled wire?
