CuNi44 Flat Hlau (ASTM C71500 / DIN CuNi44) Nickel-Copper Alloy rau cov khoom siv hluav taws xob
Product Description
CuNi44 Flat Hlau
Product Advantages thiab Qib Distinctions
CuNi44 ca hlau sawv tawm rau nws qhov tshwj xeeb hluav taws xob tiv thaiv kev ruaj ntseg thiab kev ua haujlwm txhua yam, ua rau nws xaiv zoo tshaj rau cov khoom siv hluav taws xob zoo. Piv rau cov tooj liab-nickel zoo sib xws li CuNi10 (Constantan) thiab CuNi30, CuNi44 muaj kev tiv thaiv ntau dua (49 μΩ·cm vs. 45 μΩ·cm rau CuNi30) thiab qis dua kub coefficient ntawm kev ua haujlwm (TCR), kom ntseeg tau qhov tsawg kawg nkaus tsis kam drift nyob rau hauv kub-fluctuating ib puag ncig. Tsis zoo li CuNi10, uas ua tau zoo hauv cov ntawv thov thermocouple, CuNi44 qhov sib npaug ntawm kev tsim thiab kev ruaj ntseg ua rau nws zoo tagnrho rau cov khoom siv siab, cov ntsuas ntsuas, thiab cov shunts tam sim no. Nws lub tiaj tus ntoo khaub lig-section tsim ntxiv txhim kho cov cua sov dissipation thiab kev sib cuag sib cuag piv rau cov xov hlau puag ncig, txo cov kub kub hauv cov ntawv thov tam sim no.
Standard Designations
- Alloy Qib: CuNi44 (Copper-Nickel 44).
- UNS Nr.: C71500
- DIN Txuj: DIN 17664
- ASTM Txuj: ASTM B122
Ntsiab nta
- Superior Resistance Stability: TCR ntawm ± 40 ppm / ° C (-50 ° C txog 150 ° C), ua haujlwm zoo tshaj CuNi30 (± 50 ppm / ° C) hauv kev siv precision.
- High Resistivity: 49 ± 2 μΩ·cm ntawm 20 ° C, ua kom muaj kev tswj xyuas tam sim no hauv cov qauv tsim.
- Flat Profile Cov txiaj ntsig: Ua kom thaj chaw saum npoo kom zoo dua cov cua sov; txhim kho kev sib cuag nrog substrates hauv resistor manufacturing ..
- Zoo heev Formability: tuaj yeem dov mus rau nruj qhov ntev kam rau ua (thickness 0.05mm-0.5mm, dav 0.2mm-10mm) nrog cov khoom zoo ib yam.
- Corrosion Resistance: Resistant atmospheric corrosion thiab dej tshiab raug, haum rau hnyav industrial puag ncig.
