CuNi44 / Constantan Copper Nickel Strip, Alloy Strip for Resistors & Alxanka Sawirka Featured

CuNi44 / Constantan Copper Nickel Strip, Xarigga Alloy ee Resistors & Alxanka

Sharaxaad Gaaban:

Xarig bir ah oo joogto ah oo CuNi44 ah (Copper-Nickel 55/44), isku-darka heerkulka hooseeya ee iska caabbinta (TCR < ±40 ppm/°C), EMF kuleyl sare leh iyo naxaas. Ku habboon iska caabbinta siligga saxda ah, isku-xidhka heerkulka, iyo elektroodhada alxanka iska caabbinta. Dhumucdiisu waa laga bilaabo 0.1mm ilaa 3.0mm, ballac ilaa 300mm. Si fiican u milmi kara iyo iska caabbinta daxalka.

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

Cuni44waa dahaarka naxaasta-nickel (Cu56Ni44 dahaarka) oo lagu garto iska caabin koronto oo sare, is-beddel sare iyo iska caabin daxaleed oo wanaagsan. Waxay ku habboon tahay in loo isticmaalo heerkul gaaraya 400°C
Codsiyada caadiga ah ee CuNi44 waa potentiometers-ka heerkulka deggan, rheostats-ka warshadaha, iska caabbinta bilowga matoorka korontada iyo cabbirka cadaadiska.
Isku-darka isku-dhafka heerkulka aan la saadaalin karin iyo iska caabinta sare waxay ka dhigaysaa dahaarka mid si gaar ah ugu habboon wareegga iska caabinta saxda ah.
CuNi44 waxaa laga sameeyay naxaas elektrolytic ah iyo nikkel saafi ah. Cabbirrada siligga khafiifka ah ee daawaduhu waxaa loo qoondeeyay sidaCuni45(Heerkulbeegga).
Sharaxaadda Badeecada

Xarigga Constantan oo leh iska caabin dhexdhexaad ah iyo isku-dhafka heerkulka hooseeya oo leh iska caabin fidsan/qalooc heerkul ah oo ka ballaaran "manganins". Constantan sidoo kale wuxuu muujinayaa iska caabin daxalka oo ka wanaagsan kan ganins-ka man. Isticmaalku wuxuu u janjeeraa inuu ku koobnaado wareegyada AC.

Constantan sidoo kale waa curiyaha taban ee nooca J thermocouple oo leh Iron waa togan; nooca J thermocouples waxaa loo isticmaalaa codsiyada daaweynta kulaylka. Sidoo kale, waa curiyaha taban ee nooca T thermocouple oo leh OFHC Copper togan; nooca T thermocouples waxaa loo isticmaalaa heerkulka cryogenic.
