Eureka Bare Wire 18 swg
Product Code : JA-EE-7611
Eureka Bare Wire 18 swg (SKU JA-EE-7611) is a bare copper-nickel resistance wire of 1.25 mm diameter with a low temperature coefficient, supplied in 125 g reels for making resistance coils and for resistance experiments in physics laboratories. The 18 SWG gauge suits coils that need a fairly low resistance and whose value should stay steady as they warm. JaincoLab supplies this eureka resistance wire alongside finer eureka and constantan gauges.
Specifications
Eureka Bare Wire 18 swg is made of a copper-nickel alloy of low temperature coefficient, has a diameter of 1.25 mm and is supplied bare in reels of 125 g; the listing describes it as suitable for resistance coils.

Applications of 18 SWG eureka resistance wire
Laboratories use 18 SWG eureka wire to wind resistance coils of known, stable value, to make up resistors for verifying the series and parallel laws, and as one of a set of gauges when students measure how resistance depends on the cross-sectional area of a wire.
- Winding stable resistance coils for resistance boxes and circuit boards
- Making known resistances for series and parallel combination experiments
- Measuring how resistance depends on cross-sectional area with several gauges
- Resistivity determination with a metre bridge or post office box
