The Constantan Eureka Wire is composed of the Constantan alloy, which is a combination of copper and nickel. This unique alloy has a low thermal conductivity and a high electrical resistance, making it a valuable material in various industries. Its resistance remains constant regardless of temperature changes, solidifying its reliability as a resistance alloy. Constantan is often used in resistors, thermocouples, and strain gauges for its reliable electrical and temperature-sensing properties.
