Constantan Bare Wire 16 swg
Product Code : JA-EE-7609
Constantan Bare Wire 16 swg (SKU JA-EE-7609) is a copper-nickel alloy resistance wire with a low temperature coefficient of resistance, supplied bare in 125 g reels at 1.6 mm diameter. Because its resistance changes very little as it warms, constantan is widely used for resistance coils, shunts and bridge wires in physics laboratories. JaincoLab supplies this 16 SWG constantan wire as the heaviest gauge in its resistance wire range.
Specifications
Constantan Bare Wire 16 swg is 1.6 mm in diameter, made of a copper-nickel alloy with a low temperature coefficient, supplied without insulation in 125 g reels and described as suitable for resistance coils.

Uses of 16 SWG constantan resistance wire
The 16 SWG constantan wire is used to make low-value resistance coils and shunts whose resistance stays nearly constant as they warm, and as a thick resistance wire in experiments comparing resistance with length and cross-section alongside the finer constantan and eureka gauges.
- Winding low-value resistance coils and standard resistances
- Making a shunt to convert a galvanometer into an ammeter
- Comparing resistance with length and cross-section across wire gauges
- Showing the low temperature coefficient of constantan against copper or nichrome

Frequently asked questions
What is constantan wire made of?
Constantan is a copper-nickel alloy with a low temperature coefficient of resistance.
What are the diameter and reel weight?
The 16 SWG wire is 1.6 mm in diameter and is supplied at 125 g per reel.
Why use constantan for resistance coils?
Its low temperature coefficient means the resistance of a coil changes very little as it warms during use.
Which finer gauges are available?
Constantan and eureka bare wires are also listed in finer SWG sizes down to 34 SWG, alongside nichrome and copper wires.
