Cov hlau yog siv rau kev tsim cov qauv kev tiv thaiv, precision hlau qhov txhab resistors, potentiometers, shunts thiab lwm yam hluav taws xob.
thiab cov khoom siv hluav taws xob. Qhov Copper-Manganese-Nickel alloy no muaj cov thermal electromotive quab yuam (emf) tsawg heev thiab tooj liab, uas
ua rau nws zoo tagnrho rau siv nyob rau hauv hluav taws xob circuits, tshwj xeeb tshaj yog DC, qhov twg ib tug spurious thermal emf yuav ua rau malfunctioning ntawm hluav taws xob.
khoom siv. Lub Cheebtsam nyob rau hauv uas no alloy yog siv ib txwm ua hauj lwm nyob rau hauv chav tsev kub; yog li nws qhov kub tsis tshua muaj coefficient
Kev tiv thaiv yog tswj los ntawm 15 txog 35ºC.

Manganin hlau yog tooj liab-manganese-nickel alloy (CuMnNi alloy) siv rau hauv chav tsev kub. Cov alloy yog tus cwj pwm los ntawm cov thermal electromotive force (emf) tsawg heev piv rau tooj liab.
Manganin hlau feem ntau yog siv rau kev tsim cov qauv kev tiv thaiv, precision hlau qhov txhab resistors, potentiometers, shunts thiab lwm yam khoom siv hluav taws xob thiab hluav taws xob.
