I-CuNi44 Flat Wire (ASTM C71500/DIN CuNi44) I-Nickel-Copper Alloy Yezingxenye Zogesi
Incazelo Yomkhiqizo
I-CuNi44 Flat Wire
Izinzuzo Zomkhiqizo kanye Nokwehlukaniswa Kwebanga
I-CuNi44 wire flat ivelele ngokuzinza kwayo kokumelana nogesi kanye nokusebenza komshini, okuyenza ibe ukukhetha okuphezulu kokunemba kwezingxenye zikagesi. Uma kuqhathaniswa nama-alloys e-copper-nickel afana ne-CuNi10 (Constantan) ne-CuNi30, i-CuNi44 inikeza ukumelana okuphezulu (49 μΩ·cm vs. 45 μΩ·cm ye-CuNi30) kanye ne-coefficient ephansi yezinga lokushisa lokumelana (TCR), iqinisekisa ukukhukhuleka okuncane kokumelana ezindaweni ezishintshashintshayo. Ngokungafani ne-CuNi10, ehamba phambili ezinhlelweni zokusebenza ze-thermocouple, inhlanganisela elinganiselayo ye-CuNi44 yokubumbeka nokuzinza kokumelana iyenza ifanelekele izimelaphi ezinembayo, amageji obunzima, namashunti amanje. Idizayini yayo enezingxenye eziyisicaba ithuthukisa futhi ukunqanyulwa kokushisa kanye nokufana kokuxhumana uma kuqhathaniswa nezintambo eziyindilinga, kunciphisa izindawo ezishisayo ezinhlelweni zamanje.
Ukuqokwa Okujwayelekile
- I-Alloy Grade: CuNi44 (Copper-Nickel 44).
- Inombolo ye-UNS: C71500
- I-DIN Standard: I-DIN 17664
- Izinga le-ASTM: ASTM B122
Izici Ezibalulekile
- I-Superior Resistance Stability: I-TCR engu-±40 ppm/°C (-50°C kuya ku-150°C), esebenza kahle kakhulu kune-CuNi30 (±50 ppm/°C) ezinhlelweni zokusebenza ezinembayo.
- Ukungazweli Okuphezulu: 49 ± 2 μΩ·cm ku-20°C, okuqinisekisa ukulawula kwamanje okusebenzayo kumadizayini ahlangene.
- Izinzuzo Zephrofayili Eyisicaba: Indawo eyandayo yokukhipha ukushisa okungcono; ukuxhumana okuthuthukisiwe nama-substrates ekukhiqizweni kwe-resistor
- Ukuhleleka Okuhle Kakhulu: Ingasongwa ukuze ikwazi ukubekezelela ubukhulu obuqinile (ubukhulu obungu-0.05mm–0.5mm, ububanzi bungu-0.2mm–10mm) kanye nezakhiwo ezingaguquguquki zemishini.
- I-Corrosion Resistance: Imelana nokugqwala komkhathi kanye nokuchayeka emanzini ahlanzekile, alungele izindawo zezimboni ezinonya.

Izicelo Ezijwayelekile
- I-Precision wirewound resistors kanye nama-shunts amanje
- I-Strain gauge grids namaseli okulayisha
- Izinto zokushisisa kumishini yezokwelapha
- Ukuvikela i-EMI kumasekhethi anemvamisa ephezulu
- Othintana nabo ngogesi kuzinzwa zezimoto
Sihlinzeka ngezixazululo ezilungiselelwe izidingo ezithile zobukhulu. Amasampula wamahhala (ubude obu-1m) nedatha yokusebenza ngokuqhathanisa ne-CuNi30/CuNi10 iyatholakala uma icelwa.
