CuNi44 Hlau tiaj tiaj (ASTM C71500/DIN CuNi44) Nickel-Tooj Liab Alloy rau Cov Cheebtsam Hluav Taws Xob
Kev piav qhia txog khoom
CuNi44 Hlau tiaj tus
Cov txiaj ntsig ntawm cov khoom thiab qib sib txawv
CuNi44 cov hlau tiaj tiaj sawv tawm rau nws qhov kev ruaj khov hluav taws xob zoo tshaj plaws thiab kev ua haujlwm tau zoo, ua rau nws yog qhov kev xaiv zoo dua rau cov khoom siv hluav taws xob raug. Piv rau cov hlau tooj liab-nickel zoo sib xws xws li CuNi10 (Constantan) thiab CuNi30, CuNi44 muaj kev tiv taus siab dua (49 μΩ·cm vs. 45 μΩ·cm rau CuNi30) thiab qhov kub qis dua ntawm kev tiv taus (TCR), ua kom ntseeg tau tias qhov tsis kam tsawg kawg nkaus hauv qhov kub thiab txias hloov pauv. Tsis zoo li CuNi10, uas ua tau zoo hauv kev siv thermocouple, CuNi44 qhov kev sib xyaw ua ke ntawm kev ua tau zoo thiab kev ruaj khov tiv taus ua rau nws zoo tagnrho rau cov resistors siab, cov ntsuas kev ntxhov siab, thiab cov shunts tam sim no. Nws cov qauv tsim tiaj tiaj ntxiv txhim kho kev sib kis cua sov thiab kev sib cuag sib xws piv rau cov hlau puag ncig, txo cov chaw kub hauv cov ntawv thov tam sim no siab.
Cov Npe Txheem
- Qib Alloy: CuNi44 (Tooj liab-Nickel 44)
- Tus lej UNS: C71500
- Tus Qauv DIN: DIN 17664
- ASTM Tus Qauv: ASTM B122
Cov yam ntxwv tseem ceeb
- Kev Ruaj Ntseg Zoo Tshaj Plaws: TCR ntawm ±40 ppm / ° C (-50 ° C txog 150 ° C), ua tau zoo dua CuNi30 (±50 ppm / ° C) hauv kev siv precision.
- Kev Tiv Thaiv Siab: 49 ± 2 μΩ·cm ntawm 20°C, ua kom muaj kev tswj hwm tam sim no zoo hauv cov qauv me me.
- Cov txiaj ntsig ntawm cov qauv tiaj tiaj: Ua kom thaj chaw ntawm cov khoom siv tau zoo dua thiab ua kom cov cua sov tawm tau zoo dua; ua kom muaj kev sib cuag zoo dua nrog cov khoom siv hauv kev tsim cov resistor.
- Zoo heev rau kev ua kom zoo nkauj: Muaj peev xwm dov tau kom nruj raws li qhov ntev (tuab 0.05mm–0.5mm, dav 0.2mm–10mm) nrog cov khoom siv kho tshuab zoo ib yam.
- Kev Tiv Thaiv Kev Xeb: Tiv taus kev xeb hauv huab cua thiab kev raug dej qab zib, tsim nyog rau cov chaw ua haujlwm hnyav.
