| Seawater tshaj tawm txwv | Siab dua (turbulent flow) | Nruab nrab (txog 3.5 m / s) |
| Weldability | Zoo dua (nickel cov ntsiab lus siab dua) | Zoo |
| Nqi | Siab dua | qis |
Kev taw qhia kev xaiv:Xaiv C71500 rau siab -ceev los yog dej hiav txwv turbulent, offshore platforms, tsim hluav taws xob, thiab cov ntawv thov uas yuav tsum tau muaj zog dua thiab weldability zoo dua. Xaiv C70600 rau cov dej hiav txwv nruab nrab uas qhov thermal conductivity yog qhov tseem ceeb thiab tus nqi yog qhov txwv.
Fabrication & Vuam
Weldability:Copper-nickel alloys muaj weldability zoo thiab tuaj yeem welded nrog ib txwm vuam technics tshwj tsis yog oxyacetylene welding. 70-30 (C71500) thiab C71640 alloys muaj weldability zoo dua piv rau 90-10 Cupronickel vim cov ntsiab lus ntau dua nickel.
Welding rau steel:Cupronickel alloys tuaj yeem txuas rau cov khoom siv hlau nrog cov electrodes uas muaj cov tshuaj lom neeg / cov khoom siv zoo sib xws rau cupronickel.
Kev tiv thaiv corrosion:Ob qib qhia tau hais tias zoo crevice corrosion thiab stress corrosion crack (SCC) kuj nyob rau hauv dej hiav txwv vim hais tias ntawm ib tug nyias zaj duab xis nyob rau saum npoo uas tsim tom qab raug dej hiav txwv nyob rau hauv ob peb lub lis piam.
Cryogenic kev ua haujlwm:Cupro-nickel alloys ua tau zoo ntawm qhov kub thiab txias vim muaj thermal conductivity thiab ductility zoo.
Common Cupro-Nickel Qib
| UNS npe | Alloy | Thermal conductivity (W / (m · K) | Yield zog (MPa) | Tensile zog (MPa) | |
|---|---|---|---|---|---|
| C70600 | CuNi10Fe1Mn | 90-10 | 40 | 105 | 275 |
| C71500 | CuNi30Mn1Fe | 70-30 | 29 | 125 | 360 |
