Vim li cas Inconel Kovar?

1.Kovar muaj kev siv dav hauv kev lag luam hauv hluav taws xob, xws li cov khoom siv hlau txuas nrog lub hnab ntawv tawv iav.Cov khoom no yog siv rau cov khoom siv xws li lub hwj chim raj thiab X-ray raj, thiab lwm yam.
2.In lub semiconductor kev lag luam kovar yog siv nyob rau hauv hermetically kaw tej pob khoom rau ob qho tib si integrated thiab discrete circuit devices.
3.Kovar yog muab nyob rau hauv ntau hom ntawv los pab txhawb kev tsim khoom ntawm ntau yam hlau.Nws muaj cov yam ntxwv thermal expansion txuam nrog cov iav tawv.Siv rau kev sib txuam expansion pob qij txha ntawm cov hlau thiab iav los yog ceramics.
4.Kovar alloy yog lub tshuab nqus tsev melted, hlau-nickel-cobalt, tsis tshua muaj expansion alloy uas nws cov tshuaj muaj pes tsawg leeg yog tswj nyob rau hauv nqaim txwv kom paub meej meej uniform thermal expansion zog.Kev tswj kom zoo yog ua haujlwm nyob rau hauv kev tsim cov hlau no los xyuas kom meej lub cev thiab cov cuab yeej cuab tam kom yooj yim hauv kev sib sib zog nqus nqus, stamping thiab machining.

Kovar Alloy Daim ntawv thov teb:

● Kovar alloy tau siv los ua hermetic ntsaws ruaj ruaj nrog cov iav Pyrex nyuaj thiab cov ntaub ntawv ceramic.
●Qhov no alloy tau pom dav daim ntawv thov nyob rau hauv lub hwj chim raj, microwave tubes, transistors thiab diodes.Hauv kev sib txuas sib txuas, nws tau siv rau lub pob tiaj tiaj thiab pob khoom dual-hauv-kab.
