4J29-Kovar alloy sawb Kovar bar / kovar ntawv / kovar raj

Khoom Nthuav dav

Cov Kev Lag Luam Muaj Npe: Kovar Alloy, 4J29, UNS K94610 (FeNi29Co17),29HК Kovar, KV-1,29HК-BИ, Werkstoff Nr.1.3981

Cov alloy no kuj caleed Iav ntim thiab tswj tau expansion alloy,Cov alloy muaj a linear expansion coefficient zoo ib yam li ntawd ntawm silicon boron nyuaj iav ntawm 20-450 ° C, a siab dua Curie point, thiab qhov zoo qis-kub ua qauv kev ua haujlwm ruaj khov. Cov oxide zaj duab xis ntawm lub alloy yog ntom thiab tuaj yeem ua kom zoo ntxoov los ntawm iav . Nws tsis cuam tshuam nrog mercury thiab yog tsim nyog rau siv nyob rau hauv cov mercury-muaj paug tawm. Nws yog lub ntsiab sealing qauv khoom siv rau cov cuab yeej hluav taws xob nqus.

Vim li cas Inconel Kovar?

1.Kovar muaj kev siv dav dav hauv kev lag luam hluav taws xob, xws li hlau qhov sib txuas rau cov hnab ntawv iav nyuaj. Cov ntu no yog siv rau cov khoom siv xws li cov raj fais fab thiab cov hlab xoo hluav taws xob, thiab lwm yam.
2.Nyob hauv kev lag luam semiconductor kovar siv nyob rau hauv pob ntim ntim hermetically rau ob qho kev sib xyaw thiab sib cais hauv cov Circuit Court.
3.Kovar muaj ntau cov ntawv los pab txhawb kev tsim khoom ntawm ntau qhov chaw hlau. Nws muaj cov thermal expansion cov yam ntxwv txuam nrog cov iav nyuaj. Siv rau kev sib txuas ntxiv sib txuas ntawm cov hlau thiab iav los yog ceramics.
4.Kovar alloy yog lub tshuab nqus tsev melted, hlau-npib tsib xee-cobalt, qhov nthuav dav qis uas nws cov tshuaj lom neeg muaj kev tswj tsis pub dhau qhov nqaim qis kom paub tseeb cov ua haujlwm thermal nthuav dav. Cov kev tswj xyuas tau zoo tau ua haujlwm hauv kev tsim cov hlau no kom ntseeg tau tias lub cev thiab lub cev tsis xws luag kom yooj yim hauv cov duab kos sib sib zog nqus, ntaus cim thiab cov tshuab.

Kovar Alloy Daim Teb Thov :

Ov Kovar alloy tau siv rau kev ua cov hermetic seals nrog qhov nyuaj dua Pyrex tsom iav thiab cov ntaub ntawv ceramic.
Alloy No cov hlau no tau pom daim ntawv thov dav hauv cov raj fais fab, microwave leeg, transistors thiab diodes. Hauv kev sib xyaw hauv kev ncig, nws tau siv rau pob tiaj thiab pob khoom ntawm ob tog.
