CUNI1 kobber-nikkel lav-resistens legeret tråd

CUNI1 kobber-nikkel lav-modstand legeret tråd er det foretrukne materiale til fremstilling af milliohm-niveau modstande. Det er almindeligt anvendt til strømmåling i bilelektronik og batteristyringssystemer (BMS), der producerer ekstremt lavt spændingsfald og varmetab selv under høje strømforhold. I applikationer, hvor der kun kræves en lille temperaturstigning (såsom gulvvarmesystemer, afrimningsanordninger og medicinske varmetæpper), kan CuNi1-tråd bruges som et varmeelement for at give langdistance og ensartet varmefordeling uden at generere lokale hotspots som højmodstandstråde.
