Product Description

This bare eureka (constantan) wire is a copper-nickel alloy with a low temperature coefficient of resistance, making it well suited for resistance coils and similar applications. The wire is 26 SWG (0.45mm diameter) and is supplied on a reel of 125g. Constantan wire maintains a nearly constant resistance across a wide temperature range, making it ideal for physics experiments involving resistance, Ohm's law, and the construction of precision resistance elements in educational and laboratory settings.
