Cov sib txawv sib txawv ntawm cov tooj liab siab & qis nickel cov ntsiab lus alloys nrog siab lossis qis tshwj xeeb kuj tseem ceeb rau qhov kub tsis tshua muaj coefficient ntawm kev ua haujlwm. Muaj kev ua haujlwm siab rau oxidation thiab tshuaj corrosion, cov hlau no yog siv rau cov hlau-qhov txhab precision resistors, potentiometers, ntim tswj cov cuab yeej, winding heavy-duty industrial rheostats thiab hluav taws xob tiv thaiv. Cov kev sib txawv sib txawv yog siv rau cov cua sov cables uas tsis tshua muaj neeg xyuas pib kub thiab ua cov raj vuam hauv "hluav taws xob vuam fittings".Tooj liab Manganese alloyyog siv cov khoom txheem rau precision, standard thiab shunt resistors.
