Goodfellow Constantan® Spooled Wire is a high-performance copper-nickel alloy designed for advanced research and industrial applications. This annealed wire is ideal for thermocouples, resistors, and strain gauges due to its stable electrical resistivity, which remains consistent despite temperature fluctuations. It excels in harsh environments, such as industrial furnaces and high-current applications, thanks to its durability and resistance to oxidation and corrosion. This wire is essential for sensor applications in aerospace and automotive industries, where precision is crucial. Additionally, it is widely used in research and development for prototyping sensors and electronic components, aiding advancements in materials science and engineering.
