Product Description
KPKN Thermocouple Strip (Type K Thermocouple Alloy Strip)
KPKN thermocouple strip from Huona New Material is a precision cold-rolled alloy strip specifically designed for Type K thermocouple sensors and heating elements. It consists of two matching alloy strips: KP (Chromel, positive pole) and KN (Alumel, negative pole), which together form the core of Type K thermocouples. Manufactured via precision cold rolling and vacuum annealing, it delivers stable thermoelectric properties, excellent mechanical strength, and consistent performance across a wide temperature range.
