Constantan

Constantan is an alloy made primarily of copper and nickel, known for its very stable electrical resistance across a wide temperature range. This consistency makes it ideal for precise electrical applications like thermocouples, which measure temperature, and electrical resistors. Constantan's resistance doesn't fluctuate much when heated or cooled, allowing for accurate and reliable measurements. It is also durable and resistant to corrosion, making it suitable for demanding environments. Its unique properties come from the combination of metals that maintain electrical stability, making Constantan an essential material in various scientific and industrial uses.
