Alloy 4J36: Fortifying Lub hauv paus ntawm kev ruaj ntseg hauv Precision teb nrog Ultra-Low Expansion Properties
Oct 16, 2025
Raws li cov hlau-nickel alloy uas muaj kwv yees li 36% npib tsib xee, 4J36 tau dhau los ua "kev txhawb nqa tseem ceeb" hauv ntau thaj chaw uas yuav tsum tau muaj kev ruaj ntseg thiab qhov tseeb, ua tsaug rau nws qhov tshwj xeeb nyob ze -zero expansion khoom nyob rau hauv thaj tsam ntawm -250℃mus rau 200℃. Nws lub xub ntiag txuas ntxiv los ntawm microelectronic Cheebtsam mus rau macro- nplai dav hlau, hla ntau qhov kev lag luam siab.
Nyob rau hauv lub tshav pob ntawm precision instruments thiab metrology, 4J36 ua raws li "tus neeg saib xyuas ntawm qhov tseeb"- qauv ntsuas cov cuab yeej xws li ntsuas ntsuas thiab ntsuas ntsuas ntsuas ntsuas nws los tiv thaiv qhov kub thiab txias, kom ntseeg tau cov txiaj ntsig ntsuas qhov tseeb. Cov khoom siv xws li tsom iav tsom iav tsom iav thiab laser interferometer qhia rails kuj tseem muaj cov qauv kev ruaj ntseg thaum hloov kub vim 4J36, tiv thaiv kev ntsuas qhov tseeb.
Hauv kev lag luam electronics thiab semiconductor, nws cov thermal expansion coefficient, uas phim cov ntaub ntawv xws li ceramics thiab iav, tiv thaiv semiconductor nti ntim tsev thiab txhuas thav ntawv los ntawm thermal stress cracking. Thaum lub sij hawm lithography thiab etching cov txheej txheem hauv kev tsim hluav taws xob sib xyaw ua ke, qhov ruaj khov ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob kuj tau lees paub los ntawm 4J36.
Lub aerospace thiab kev tiv thaiv kev lag luam tseem nyob ntawm qhov "kev ruaj ntseg cuab yeej": satellite antenna mounts thiab infrared detector structural Cheebtsam ua haujlwm zoo nyob rau hauv qhov kub thiab txias sib txawv hauv qhov chaw, thaum gyroscopes hauv missile guidance systems thiab optical brackets nyob rau hauv laser sights cia siab rau nws low expansion khoom los xyuas kom meej aiming raug nyob rau hauv huab mob.
Nws lub xub ntiag kuj tseem muaj pov thawj hauv cov khoom siv kho mob thiab lub zog engineering: rotating Cheebtsam ntawm CT scanners thiab MRI cov cav tov tswj qhov tseeb los ntawm 4J36; Hloov pauv qhov chaw ntawm LNG cia tso tsheb hlau luam thiab lub tes tsho tiv thaiv thermocouple hauv cov khoom siv hluav taws xob siv los txo qhov kub ntawm qhov sib txawv ntawm kev ntxhov siab, ntxiv dag zog rau kev nyab xeeb. Txawm tias lub log sib npaug hauv siab - kawg saib thiab lub lens mounts hauv cov cuab yeej kho qhov muag tau txais txiaj ntsig los ntawm nws, txhim kho lub sijhawm raug thiab cov duab ruaj khov.
Los ntawm cov chaw soj nstuam mus rau qhov chaw, los ntawm microchips mus rau cov cuab yeej loj, 4J36, nrog rau nws nyob ze -zero expansion "superpower," ua haujlwm raws li "pob zeb pom tsis pom" tiv thaiv qhov tseeb thiab kev ruaj ntseg, tsis tu ncua kev txhim kho kev lag luam siab -precision industries.
