Constantan Bare Wire 22 Swg
Product Code : JA-EE-7615
Constantan Bare Wire 22 Swg (SKU JA-EE-7615) is a bare copper-nickel resistance wire, 0.7 mm in diameter, with a low temperature coefficient, supplied in 125 g reels. The 22 SWG gauge gives a higher resistance per metre than the 16 SWG constantan, which makes it convenient for winding resistance coils of moderate value and for experiments that compare wires of different thickness. JaincoLab supplies this 22 SWG constantan wire to school and college physics laboratories.
Specifications
Constantan Bare Wire 22 Swg is 0.7 mm in diameter, made of a copper-nickel alloy of low temperature coefficient, supplied bare in 125 g reels and described in the listing as suitable for resistance coils.

Applications of 22 SWG constantan wire
Teachers use 22 SWG constantan wire to wind resistance coils for boards and resistance boxes, and to compare it with thicker and thinner constantan or eureka wires of equal length, so students can see that resistance falls as the cross-sectional area of the wire increases.
- Winding moderate-value resistance coils for boards and resistance boxes
- Comparing resistance of wires of equal length but different thickness
- Verifying Ohm’s law with a measured length of wire
- Resistivity experiments with a metre bridge
