CuNi44 / Constantan Copper Nickel Strip, Alloy Strip yeResistors & Welding

Tsananguro pfupi:

CuNi44 constantan alloy strip (Copper-Nickel 55/44), ine resistance yakaderera (TCR < ±40 ppm/°C), high thermal EMF vs copper. Yakanakira ma resistor e wirewound accuracy, thermocouples, uye resistance welding electrodes. Ukobvu kubva pa 0.1mm kusvika 3.0mm, upamhi hunosvika 300mm. Inogoneka kusvira uye inodzivirira ngura.

Chiyero cheAlloy:CuNi44 (Constantan)

Kuumbwa:Cu ~55%, Ni ~44%, Mn ~1%

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

Kuramba:0.49 μΩ·m @20°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,)

Cuni44isimbi yemhangura-nickel (Cu56Ni44 alloy) ine simba rekudzivirira magetsi, simba rakawanda uye simba rakanaka rekudzivirira ngura. Yakakodzera kushandiswa patembiricha inosvika 400°C
Mashandisirwo akajairika eCuNi44 ipotentiometers dzinogara kwenguva refu pakupisa, ma industrial rheostats, electric motor starter resistances uye strain gauge.
Kusanganiswa kwekushisa kushoma uye resistivity yakakwira kunoita kuti alloy ive yakakodzera kutenderedzwa kwe resistors dzakarurama.
CuNi44 inogadzirwa nemhangura yemagetsi uye nickel yakachena. Kana iri waya dzakatetepa, chisanganiswa chacho chinoonekwa seCuni45(Thermocouple).
Tsananguro yeChigadzirwa

Constantan Strip ine resistivity iri pakati nepakati uye coefficient yakaderera yekudzivirira ine flat resistance/tembiricha curve pamusoro pemhando yakakura kupfuura "manganins". Constantan inoratidzawo ngura iri nani kupfuura man ganins. Mashandisirwo ayo anowanzo kuganhurirwa kuma ac circuits.

Constantan zvakare chinhu chisina kunaka chemhando yeJ thermocouple ine Iron iri yakanaka; ma thermocouple emhando yeJ anoshandiswa mukurapa kupisa. Zvakare, chinhu chisina kunaka chemhando yeT thermocouple ine OFHC Copper ndiyo yakanaka; ma thermocouple emhando yeT anoshandiswa pakupisa kwe cryogenic.
