T1 Thermocouple Alloy Foil (Ni90/Cr10)

T1 Thermocouple Alloy Foil (Ni90/Cr10) offers high-temperature resilience, oxidation resistance, and consistent thermoelectric characteristics, making it ideal for thin, precision thermal measurement elements. Its foil format allows for lightweight, flexible integration into temperature sensing devices, heating panels, and calibration tools. Industries use it in metallurgical analysis, industrial furnace monitoring, and aerospace temperature control systems. Specific applications include laminated thermocouple strips, custom-shaped heater foils, and calibration sheets for thermal standards. In research, it is deployed in micro-scale thermal measurement setups, high-precision thermoelectric property evaluations, and thin-film heating experiments. The combination of dimensional precision, mechanical stability, and thermal accuracy makes it indispensable in both applied and experimental thermal engineering contexts.
