Product Description
CuNi44 Strip
Product Overview
CuNi44 xov, ib qho kev ua tau zoo ntawm tooj liab-nickel alloy sawb tsim thiab tsim los ntawm Tankii Alloy Khoom, nta cov ntsiab lus nominal npib tsib xee ntawm 44% nrog tooj liab ua lub hauv paus hlau. Leveraging peb cov txheej txheem txias-dov thiab precision annealing technologies, cov sawb no ua tiav nruj me ntsis kam rau ua thiab cov khoom zoo ib yam thoob plaws batches. Nws koom ua ke tshwj xeeb hluav taws xob tiv thaiv kev ruaj ntseg, superior corrosion kuj, thiab zoo heev formability-striking ib tug zoo meej tshuav nyiaj li cas rau precision hluav taws xob Cheebtsam, sensor ntsiab, thiab industrial hardware uas xav tau mus ntev kev cia siab.

Cov txiaj ntsig tseem ceeb (vs. Zoo sib xws Alloys)
CuNi44 xovsawv tawm hauv tsev neeg tooj liab-nickel alloy rau nws cov phiaj xwm kev ua tau zoo:
- Ultra-Stable Hluav Taws Xob Resistance: Resistivity ntawm 49 ± 2 μΩ·cm ntawm 20 ° C thiab tsis tshua muaj kub coefficient ntawm tsis kam (TCR: ± 40 ppm / ° C, -50 ° C txog 150 ° C) - deb superior rau CuNi30 (TCR ± 50 ppm / ° C) thiab cov khoom siv tsis zoo
- Superior Corrosion Resistance: Withstands atmospheric corrosion, dej tshiab, thiab tshuaj lom neeg ib puag ncig; dhau 1000-teev ASTM B117 ntsev tshuaj ntsuam nrog negligible oxidation, outperforming tooj dag thiab bronze nyob rau hauv hnyav industrial chaw.
- Zoo heev Formability: High ductility enables txias dov rau nyias gauges (0.01mm) thiab complex stamping (xws li, resistor grids, sensor clips) tsis muaj cracking - ntau workable tshaj high-hardness alloy strips zoo li CuNi50.
- Balanced Mechanical Properties: Tensile lub zog ntawm 450-550 MPa (annealed) thiab elongation ≥25% tawm tsam kev sib haum xeeb ntawm cov qauv kev ruaj ntseg thiab kev ua haujlwm, haum rau ob qho tib si load-bearing thiab precision-machined Cheebtsam.
- Nqi-Effective Precision: Muab kev ua tau zoo piv rau cov hlau muaj txiaj ntsig zoo (xws li, manganin) ntawm tus nqi qis, ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob ntau.
