Product Description
CuNi44 Ntawv Nyiaj (0.0125mm Thickness × 102mm Dav)
Product Overview
CuNi44 foil(0.0125mm × 102mm), qhov no tooj liab-nickel tsis kam alloy, tseem hu ua constantan, yog tus cwj pwm los ntawm cov hluav taws xob siab.
ua ke nrog ib tug me me kub coefficient ntawm cov kuj. Cov alloy no tseem qhia tau tias muaj zog tensile siab
thiab tiv thaiv corrosion. Nws tuaj yeem siv tau ntawm qhov kub txog li 600 ° C hauv huab cua.

Cov txiaj ntsig tseem ceeb (vs. Standard CuNi44 Foils)
Qhov no 0.0125mm × 102mm CuNi44 ntawv ci sawv tawm rau nws lub hom phiaj ultra-nyias thiab ruaj-dav tsim:
- Ultra-Thin Precision: 0.0125mm thickness (sib npaug rau 12.5μm) ua tiav kev lag luam-ua thinness, ua kom cov khoom siv hluav taws xob me me yam tsis muaj kev cuam tshuam cov khoom siv dag zog.
- Kev ua haujlwm ruaj khov: Resistivity ntawm 49 ± 2 μΩ·cm ntawm 20 ° C thiab tsis tshua muaj kub coefficient ntawm kev ua haujlwm (TCR: ± 40 ppm / ° C, -50 ° C txog 150 ° C) - kom ntseeg tau tias tsis tshua muaj siab drift hauv high-precision ntsuas scenarios, outperforming thinner non-alloyils.
- Strict Dimensional Control: Thickness kam rau ua ntawm ± 0.0005mm thiab dav kam rau ua ntawm ± 0.1mm (102mm taag dav) tshem tawm cov khoom pov tseg hauv cov kab ntau lawm, txo cov nqi xa khoom rau cov neeg siv khoom.
- Zoo heev Formability: High ductility (elongation ≥25% nyob rau hauv lub xeev annealed) tso cai rau complex micro-stamping thiab etching (xws li, nplua resistor grids) tsis muaj cracking - tseem ceeb rau precision hluav taws xob manufacturing.
- Corrosion Resistance: Hla 500-teev ASTM B117 ntsev tshuaj tsuag tshuaj ntsuam nrog tsawg oxidation, ua kom ntseeg tau ntev nyob rau hauv cov av noo lossis tshuaj lom neeg ib puag ncig.
