I-China CuNi44 / Constantan Copper Nickel Strip, i-Alloy Strip yeeResistors kunye noMveliso weWelding kunye neFektri

I-CuNi44 / Constantan Copper Nickel Strip, I-Alloy Strip yeeResistors kunye neWelding

Inkcazo emfutshane:

I-CuNi44 constantan alloy strip (Copper-Nickel 55/44), i-coefficient yokumelana nobushushu obuphantsi (TCR < ±40 ppm/°C), i-EMF ephezulu yobushushu xa ithelekiswa ne-copper. Ilungele ii-resistors ezichanekileyo zee-wirewound, ii-thermocouples, kunye nee-electrodes ze-resistance welding. Ubukhulu ukusuka kwi-0.1mm ukuya kwi-3.0mm, ububanzi ukuya kuthi ga kwi-300mm. I-solderability elungileyo kunye nokumelana nokugqwala.

Ibanga le-alloy:I-CuNi44 (iConstantan)

Ulwakhiwo:I-Cu ~ 55%, i-Ni ~ 44%, i-Mn ~ 1%

I-TCR (±40 ppm/°C):≤ ±40 ppm/°C (20-60°C)

Ukuxhathisa:0.49 μΩ·m @20°C

I-EMF yobushushu vs i-Cu:~42 μV/°C (0-100°C)

Ingcaciso yeMveliso

I-Cuni44 CU-NI-Mn Copper Nickel Alloy Resistance Constantan Strip
(Igama eliqhelekileyo:Constantan CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,)

I-Cuni44yi-alloy ye-copper-nickel (i-Cu56Ni44 alloy) ephawulwa kukumelana okuphezulu kombane, ukuguguleka okuphezulu kunye nokumelana okuhle kokugqwala. Ifanelekile ukusetyenziswa kumaqondo obushushu afikelela kwi-400°C
Iindlela eziqhelekileyo zokusetyenziswa kweCuNi44 zii-potentiometers ezizinzileyo kubushushu, ii-rheostats zemizi-mveliso, ii-electric motor starter resistances kunye ne-strain gauge.
Ukudibanisa i-coefficient yobushushu obungenamsebenzi kunye ne-resistivity ephezulu kwenza i-alloy ifaneleke ngokukodwa ekujijeni kwe-resistors ezichanekileyo.
I-CuNi44 yenziwe nge-electrolytic copper kunye ne-nickel ecocekileyo. Ngobukhulu obuncinci beengcingo, i-alloy ibizwa ngokuba yi-I-Cuni45(I-Thermocouple).
Ingcaciso yeMveliso

I-Constantan Strip enokumelana okuphakathi kunye nokumelana okuphantsi kobushushu kunye nokumelana okuthe tyaba/ubushushu obujikeleze uluhlu olubanzi kune-"manganins". I-Constantan ikwabonisa ukumelana okungcono kokugqwala kune-man ganins. Ukusetyenziswa kudla ngokukhawulelwa kwiisekethe ze-ac.

IConstantan ikwalilungu elingalunganga le-thermocouple yohlobo lwe-J apho i-Iron iyinto elungileyo; ii-thermocouple zohlobo lwe-J zisetyenziswa kwiindlela zokunyanga ubushushu. Kwakhona, lilungu elingalunganga le-thermocouple yohlobo lwe-T ene-OFHC Copper elilungileyo; ii-thermocouple zohlobo lwe-T zisetyenziswa kumaqondo obushushu aphantsi.
