Waya Yakatsetseka yeCuNi44 (ASTM C71500/DIN CuNi44) Nickel-Copper Alloy yeZvikamu zveMagetsi
Tsananguro yeChigadzirwa
Waya Yakatsetseka yeCuNi44
Zvakanakira Chigadzirwa uye Kusiyana Kwemagiredhi
Waya yakatsetseka yeCuNi44 inoonekwa nekugadzikana kwayo kwakanyanya kwekudzivirira magetsi uye kushanda zvakanaka kwemuchina, zvichiita kuti ive sarudzo yepamusoro yezvikamu zvemagetsi zvakarurama. Kana ichienzaniswa ne copper-nickel alloys dzakafanana seCuNi10 (Constantan) neCuNi30, CuNi44 inopa resistivity yakakwira (49 μΩ·cm vs. 45 μΩ·cm yeCuNi30) uye tembiricha yakaderera yekudzivirira (TCR), zvichiita kuti resistance drift isanyanya kuderera munzvimbo dzinochinja-chinja tembiricha. Kusiyana neCuNi10, iyo inobudirira mukushandiswa kwe thermocouple, musanganiswa wakaenzana weCuNi44 wekugadzirisa uye kugadzikana kwekudzivirira kunoita kuti ive yakakodzera kune resistor dzakanyatsojeka, strain gauges, uye current shunts. Dhizaini yayo yakatsetseka inowedzera kuwedzera kupisa uye kufanana kwekubatana zvichienzaniswa newaya dzakatenderera, zvichideredza nzvimbo dzinopisa mukushandiswa kwe high-current.
Mazita Akajairika
- Giredhi reAlloy: CuNi44 (Copper-Nickel 44)
- Nhamba yeUNS: C71500
- Muyero weDIN: DIN 17664
- ASTM Standard: ASTM B122
Zvinhu Zvikuru
- Kugadzikana Kwepamusoro-soro: TCR ye ±40 ppm/°C (-50°C kusvika 150°C), inoshanda kupfuura CuNi30 (±50 ppm/°C) mukushandiswa kwakarurama.
- Kudzivirira Kwakanyanya: 49 ± 2 μΩ·cm pa20°C, zvichiita kuti magetsi adzorwe zvakanaka mumagadzirirwo akamanikana.
- Mabhenefiti eFlat Profile: Kuwedzera kwenzvimbo yepamusoro kuti kupisa kupararire zviri nani; kunatsiridza kusangana nesubstrates mukugadzira resistor.
- Kugadzirwa Kwakanaka Kwazvo: Inogona kupetwa kusvika pakakwirira (ukobvu 0.05mm–0.5mm, upamhi 0.2mm–10mm) ine hunhu hwakafanana hwemakanika.
- Kuramba Kuora: Inodzivirira ngura yemumhepo uye mvura yakachena, yakakodzera nzvimbo dzakaoma dzemaindasitiri.
Magadzirirwo ehunyanzvi
| Hunhu | Kukosha |
| Hukobvu hwemhando | 0.05mm – 0.5mm |
| Upamhi hweRange | 0.2mm – 10mm |
| Kushivirira Ukobvu | ±0.001mm (≤0.1mm); ±0.002mm (>0.1mm) |
| Kushivirira Kwakafara | ± 0.02mm |
| Chiyero cheAspect (Upamhi: Ukobvu) | 2:1 – 20:1 (zviyero zvemutengi zviripo) |
| Simba reKusimba | 450 – 550 MPa (yakavharirwa) |
| Kureba | ≥20% (yakabviswa) |
| Kuoma (HV) | 130 – 170 (yakabviswa); 210 – 260 (yakaoma hafu) |
Kuumbwa kweMakemikoro (Kazhinji, %)
| Chinhu | Zviri Mukati (%) |

Magadzirirwo eChigadzirwa
| Chinhu | Tsanangudzo |
| Kupedzisa Kwepamusoro | Yakanamirwa zvakanaka (Ra ≤0.2μm) |
| Fomu Rekupa | Marongero anoenderera mberi (50m - 300m) kana kureba kwekucheka |
| Kurongedza | Yakavharirwa nepepa rekudzivirira kuoresa; mapurasitiki anoputirwa |
| Sarudzo dzekugadzirisa | Kucheka, kunama, kana kuputira zvinodzivirira muviri |
| Kutevedzera mitemo | RoHS, REACH certification; mishumo yebvunzo yezvinhu iripo |
Maitiro Akajairika
- Zvinodzivirira waya zvine tambo chaiyo uye zvinodzivirira magetsi
- Magridhi ekuyera strain uye masero ekutakura
- Zvinhu zvinodziya mumidziyo yekurapa
- Kudzivirira kweEMI mumasekete ane mafrequency akakwira
- Kusangana kwemagetsi muma sensor emotokari
Tinopa mhinduro dzakagadzirirwa zvinodiwa zvakasiyana-siyana. Samples dzemahara (1m kureba) uye data rekuenzanisa mashandiro neCuNi30/CuNi10 zvinowanikwa kana zvakumbirwa.
