Cuni44 CU-NI-Mn Tooj Liab Nickel Alloy tsis kam Constantan Strip
(Common Name: Constantan CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, Cu-Ni 102, Cu-Ni 44, Konstantan,)

Cuni44yog ib qho hlau tooj liab-nickel (Cu56Ni44 alloy) uas muaj lub zog hluav taws xob siab, ductility siab thiab zoo corrosion tsis kam. Nws yog tsim rau siv ntawm qhov kub txog li 400 ° C
Cov ntawv thov ib txwm muaj rau CuNi44 yog cov ntsuas kub-ruaj khov potentiometers, kev lag luam rheostats, lub cev muaj zog hluav taws xob pib resistances thiab strain gauge.
Qhov kev sib xyaw ua ke ntawm cov coefficient kub tsis tseem ceeb thiab kev tiv taus siab ua rau cov hlau sib xyaw tshwj xeeb tshaj yog rau kev sib txuas ntawm cov resistors precision.
CuNi44 yog tsim los ntawm electrolytic tooj liab thiab nickel ntshiab. Hauv cov hlau me me, cov hlau no yog xaiv uaCuni45(Lub Thermocouple).
Kev piav qhia txog khoom

Constantan Strip nrog qhov nruab nrab resistivity thiab qis kub coefficent ntawm kev tiv thaiv nrog lub tiaj tus tsis kam / kub nkhaus hla ntau dua li "manganins". Constantan kuj qhia tau tias muaj kev tiv thaiv corrosion zoo dua li txiv neej ganins. Kev siv feem ntau raug txwv rau ac circuits.

Constantan kuj yog qhov tsis zoo ntawm hom J thermocouple nrog Iron yog qhov zoo; hom J thermocouples siv rau hauv kev kho cua sov. Tsis tas li ntawd, nws yog qhov tsis zoo ntawm hom T thermocouple nrog OFHC Tooj liab yog qhov zoo; hom T thermocouples siv rau ntawm qhov kub cryogenic.
