Evanohm® Coil

Evanohm® Coil is a precision resistance alloy composed of approximately 75% nickel, 20% chromium, 2.5% copper, and 2.5% aluminum, engineered for exceptional electrical stability and minimal resistivity drift across a wide range of operating conditions. It offers excellent thermal stability, with resistance showing minimal change at cryogenic temperatures, and displays negligible magnetoresistance even under intense magnetic fields. These properties make it ideal for applications in precision electronics, metrology, and high-reliability sensing systems. Specific uses include fabrication of precision resistors for measurement instrumentation, stable resistance elements in cryogenic sensors, and components for aerospace-grade electronic control systems. In research, Evanohm® Coil is valued for enabling accurate experimental setups where resistance consistency is critical, such as in low-temperature physics experiments and calibration devices. Its combination of temperature stability, magnetic insensitivity, and manufacturing adaptability ensures its strategic role in advancing both scientific measurement capabilities and industrial precision engineering.
