Hlau nickelyog ib yam khoom siv ua haujlwm tau zoo uas nws muaj nqis nyob rau hauv nws qhov kev sib xyaw ua ke ntawm cov khoom siv lub cev thiab tshuaj - ntau dua li cov hlau ib txwm muaj xws li tooj liab lossis txhuas - ua rau nws ua tau raws li qhov xav tau ntawm ntau yam kev lag luam, los ntawm kev tsim kho aerospace mus rau cov khoom siv kho mob precision. Hauv qab no yog cov ntsiab lus ntxaws ntawm nws cov tsav tsheb tseem ceeb, txhawb nqa los ntawm cov lus qhia txhim kho thiab cov xwm txheej siv:

Qhov Ntsuas Tus Nqi Tseem Ceeb	Kev Ua Tau Zoo thiab Cov Lus Qhia Tshwj Xeeb	Cov Ntawv Thov Ib Txwm Muaj
Kev Ruaj Khov Zoo Kawg Nkaus	- Tiv taus kub: -270°C txog 1,000°C (siv tas mus li; nickel ntshiab txog li 600°C, Ni-Cr alloy txog li 1,000°C)- Tiv taus xeb: Tiv taus 3.5% NaCl kua (dej hiav txwv simulated) thiab 5% dilute sulfuric acid, tsis pom xeb tom qab 1,000 teev ntawm kev sim- Lub zog tensile: 400–900 MPa (kho tau los ntawm kev sib xyaw, tsim nyog rau kev siv hauv kev lag luam hnyav)	Kev siv dav hlau (cov khoom siv hluav taws xob ntawm lub cav, cov xov hlau txias ntawm lub turbine), kev tsim kho hauv hiav txwv (cov xov hlau teeb liab ntawm lub platform offshore, cov khoom tiv thaiv xeb ntawm lub cev nkoj), kev ua cov tshuaj lom neeg (cov kauj cua sov ntawm lub nkoj ua haujlwm, cov ntsuas dej tsis kam rau kua qaub)
Kev Ua Haujlwm Txhim Khu Kev	- Kev ua hluav taws xob siab: 14–22 S/m (nickel ntshiab ntawm 25°C, ua kom ruaj khov rau kev xa hluav taws xob)- Kev ua hluav taws xob thermal: 90–110 W/(m·K) (sib npaug ntawm kev ua haujlwm hloov cua sov rau cov khoom cua sov thiab kev tswj hwm thermal)- Kev ywj pheej: Yooj yim rub mus rau hauv cov xov hlau zoo (mus txog 0.01 hli txoj kab uas hla) nrog kev kam rau siab sib xws (±0.002 hli),	Cov khoom siv hluav taws xob (kev sib txuas ntawm 5G lub voj voog, cov xov hlau sensor tsheb), cov khoom siv cua sov (cov cub tawg sintering hauv kev lag luam, cov tub ntxhais ua kom sov dej hauv tsev), cov khoom siv kho mob (cov xov hlau rau lub plawv dhia, cov raj xa dej insulin)
Kev Hloov Kho Tau Ntau Yam	- Cov hlau sib xyaw uas koj xaiv tau: Ni-Cr (80/20 piv rau kev tiv taus cua sov zoo dua), Ni-Fe (42/58 piv rau kev nthuav dav cua sov qis), Ni-Cu (70/30 piv rau kev tiv taus xeb zoo dua) - Sib xws nrog cov txheej txheem vuam/sib tsoo (txhawb kev sib koom ua ke rau hauv cov rooj sib dhos nyuaj) - Kev ua haujlwm ruaj khov hauv qhov chaw kub heev (av noo siab, siab qis, cuam tshuam hluav taws xob)	Tsheb (EV roj teeb bus bars, cov pa roj tawm kub sensors), lub zog rov ua dua tshiab (solar panel ribbon connectors, wind turbine generator coils), instrumentation (precision pressure gauge springs, atomic absorption spectrometer filaments)

1. Kev Ntseeg Siab Hauv Kev Lag Luam: Txo Lub Sijhawm Tsis Ua Haujlwm

Cov khoom siv tiv taus qhov kub thiab txias heev thiab xeb ua rau lub neej ua haujlwm ntev hauv cov xwm txheej hnyav. Piv txwv li, ib lub Hoobkas tshuaj lom neeg hauv Southeast Asia tau hloov cov xov hlau stainless hlau ib txwm nrog peb cov xov hlau nickel rau cov sensors reaction vessel - yav dhau los, cov xov hlau xeb txhua 6 lub hlis, ua rau $ 30,000 hauv lub sijhawm tsis ua haujlwm rau ib qho kev hloov pauv; tam sim no, peb cov xov hlau nickel kav ntev dua 3+ xyoo, txiav cov nqi kho los ntawm 40% txhua xyoo. Hauv kev tsav dav hlau, peb cov xov hlau nickel ua raws li ASTM B162 cov qauv, ua tau raws li Boeing thiab Airbus cov kev cai nyab xeeb nruj rau cov khoom tseem ceeb ntawm lub cav.

2. Kev Ua Tau Zoo Txog Kev Siv Tshuab: Pab Kom Muaj Kev Tsim Kho Tshiab

Nrog rau cov kab uas me me thiab kev coj ua hluav taws xob sib xws, cov hlau nickel yog qhov tseem ceeb rau cov ntawv thov siab. Cov chaw tsim khoom siv hluav taws xob vam khom nws rau cov voj voog 5G me me, qhov twg txawm tias 0.001 hli ntawm qhov yuam kev tuaj yeem cuam tshuam kev xa xov; peb cov hlau qhov kev kam rau siab ua kom muaj kev sib txuas ruaj khov 99.9%. Rau cov neeg tsim khoom siv kho mob, peb cov hlau nickel ua tau raws li ISO 10993 biocompatibility cov qauv - kuaj xyuas kom tsis muaj cytotoxicity lossis khaus cov ntaub so ntswg, ua rau nws muaj kev nyab xeeb rau kev siv mus sij hawm ntev.

3. Kev Siv Nyiaj Tau Zoo: Tus Nqi Mus Ntev Dhau Qhov Kev Nqis Peev Thaum Pib

Txawm hais tias cov hlau nickel muaj tus nqi siab dua 25-30% piv rau cov hlau tooj liab, nws qhov ruaj khov ua rau muaj kev txuag nyiaj mus sij hawm ntev. Rau cov platforms hauv dej hiav txwv, cov hlau tooj liab yuav tsum tau hloov txhua 2-3 xyoos vim yog xeb dej hiav txwv; peb cov hlau nickel tiv taus xeb tau ntau tshaj kaum xyoo, txo cov nqi tag nrho ntawm lub neej los ntawm 55%. Tsis tas li ntawd, peb cov hlau alloys uas hloov kho tau cia cov neeg siv khoom zam kev tsim kho ntau dhau - rau lub tuam txhab tsim vaj huam sib luag hnub ci uas xav tau kev tiv thaiv xeb nruab nrab, peb pom zoo kom siv cov hlau Ni-Cu uas pheej yig (pheej yig dua 15% piv rau Ni-Cr siab) uas tseem ua tau raws li lawv lub hom phiaj 25 xyoo.

4. Kev Ruaj Ntseg: Txhawb Nqa Cov Kev Pib Ntsuab

Cov hlau nickel yog 100% rov ua dua tshiab, nrog rau 98% rov qab tau hauv kev siv dua tshiab hauv kev lag luam - ua raws li lub hom phiaj thoob ntiaj teb-xoom. Nws qhov kev ua haujlwm thermal siab kuj txo qhov kev siv hluav taws xob: peb cov hlau nickel-chromium alloy ua tiav 95% thermal conversion efficiency (vs. 75% rau stainless hlau), txhais tau tias lub cub tawg 150kW kev lag luam siv peb cov hlau txuag tau 40,000 kWh ntawm lub zog txhua xyoo, sib npaug rau kev txiav 28 tons ntawm CO₂ emissions. Qhov no ua rau cov hlau nickel yog qhov kev xaiv ruaj khov rau cov lag luam uas xav txog ib puag ncig.
