Cov tooj liab-raws li tsis tshua muaj hluav taws xob cua sov alloy yog dav siv nyob rau hauv low-voltage circuit breaker, thermal overload relay, thiab lwm yam khoom siv hluav taws xob tsawg. Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob tsawg. Cov ntaub ntawv tsim los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev ua haujlwm zoo sib xws thiab kev ruaj ntseg zoo dua. Peb tuaj yeem muab txhua yam ntawm cov hlau puag ncig, tiaj tus thiab cov ntaub ntawv.

CuNi40 (6J40)
Constantanyog CuNi40, tseem hu ua 6J40, nws yog cov hlau tsis kam uas feem ntau yog ua los ntawm tooj liab thiab npib tsib xee.
Nws muaj qhov tsis tshua muaj siab kub coefficient, dav ua haujlwm kub (500 hauv qab), zoo machiningproperty, anti-corrosive thiab yooj yim braze vuam.

Lub alloy yog non-magnetic. Nws yog siv rau hluav taws xob regenerator qhov sib txawv ntawm cov resistor thiab cov strain resistor,
potentiometers, cua sov xov hlau, cua sov cables thiab mats. Ribbons yog siv rau cua sov ntawm bimetals. Lwm daim ntawv thov yog kev tsim cov thermocouples vim tias nws txhim kho lub zog hluav taws xob siab (EMF) hauv kev koom tes nrog lwm cov hlau.

Copper nickel alloy series: Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44.
