China CuNi44 / Constantan Copper Nickel Strip, Alloy Strip for Resistors & Welding Manufacture and Factory

Mzere wa CuNi44 / Constantan Copper Nickel, Mzere wa Alloy wa Resistors & Welding

Kufotokozera Kwachidule:

CuNi44 constantan alloy strip (Copper-Nickel 55/44), coefficient yotsika kutentha (TCR < ±40 ppm/°C), EMF yotenthetsa kwambiri poyerekeza ndi mkuwa. Yabwino kwambiri pa ma resistors a waya, ma thermocouples, ndi ma electrode oteteza kuuma. Kukhuthala kuyambira 0.1mm mpaka 3.0mm, m'lifupi mpaka 300mm. Kutha kusungunuka bwino komanso kukana dzimbiri.

Gulu la aloyi:CuNi44 (Constantan)

Kapangidwe kake:Cu ~ 55%, Ni ~ 44%, Mn ~ 1%

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

Kukana:0.49 μΩ·m @20°C

Kutentha kwa EMF vs Cu:~42 μV/°C (0-100°C)

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

Cuni44ndi aloyi ya mkuwa ndi nickel (Cu56Ni44 alloy) yomwe imadziwika ndi kukana magetsi kwambiri, kusinthasintha kwamphamvu komanso kukana dzimbiri bwino. Ndi yoyenera kugwiritsidwa ntchito kutentha mpaka 400°C.
Ntchito zomwe zimagwiritsidwa ntchito kwambiri pa CuNi44 ndi monga potentiometers zokhazikika pa kutentha, ma rheostats a mafakitale, kukana kwa magetsi ndi strain gauge.
Kuphatikiza kwa kutentha kochepa komanso kukana kwakukulu kumapangitsa kuti alloy ikhale yoyenera kwambiri pakuzungulira kwa zotsutsana molondola.
CuNi44 imapangidwa ndi mkuwa wa electrolytic ndi nickel yoyera. Mu kukula kwa waya wopyapyala, alloy imatchulidwa kutiCuni45(Thermocouple).

Constantan Strip yokhala ndi mphamvu yolimbana ndi kutentha pang'ono komanso mphamvu yotsika yolimbana ndi kutentha kwambiri komanso mphamvu yolimbana ndi kutentha kwambiri kuposa "manganins". Constantan imasonyezanso kukana dzimbiri bwino kuposa ma genins a man. Ntchito zake nthawi zambiri zimakhala zochepa pa ma ac circuits.

Constantan ndi chinthu choyipa cha mtundu wa J thermocouple pomwe Iron ndiye chinthu chabwino; ma thermocouple a mtundu wa J amagwiritsidwa ntchito pochiza kutentha. Komanso, ndi chinthu choyipa cha mtundu wa T thermocouple yokhala ndi OFHC Copper chomwe ndi chabwino; ma thermocouple a mtundu wa T amagwiritsidwa ntchito pa kutentha kwa cryogenic.
