I-4J29-Kovar i-alloy strip ye-Kovar bar / i-kovar sheet / ityhubhu ye-kovar

Iinkcukacha zeMveliso

Amagama oRhwebo oluQhelekileyo:Kovar Alloy,4J29,UNS K94610(FeNi29Co17),29HК Kovar,KV-1,29HК-BИ,Werkstoff Nr.1.3981

Le alloy kwakhona caleed Glass itywinwe kwaye ilawulwa ialloy yokwandisa,Ingxubevange ine ai-coefficient yokwandiswa komgcaefana naleyo ye-silicon boron iglasi eqinile kwi-20-450 ° C, aindawo ephezulu yeCurie, kunye nokuzinza kolwakhiwo oluphantsi lobushushu obuphantsi.Ifilimu ye-oxide ye-alloy ixinene kwaye ingaba kakuhlemanzingeiglasi.Ayidibanisi ne-mercury kwaye ifanelekile ukusetyenziswa kwiimitha zokukhupha i-mercury-containing.Yeyona nto iphambili yokutywinwa kwesakhiwo sezixhobo zokufunxa zombane.

Kutheni uInonel Kovar ?

I-1.Kovar inosetyenziso olubanzi kushishino lwe-electronics, njengamalungu esinyithi adityaniswe kwiimvilophu zeglasi enzima.Ezi nxalenye zisetyenziselwa izixhobo ezifana neetyhubhu zamandla kunye neetyhubhu ze-X-ray, njl.
I-2.Kwishishini le-semiconductor i-kovar isetyenziswa kwiipakethi ezitywinwe nge-hermetically kuzo zombini izixhobo zesekethe ezidibeneyo kunye ne-discrete.
I-3.Kovar inikezelwa kwiintlobo ezahlukeneyo zokuququzelela ukuveliswa ngokufanelekileyo kweendawo ezahlukeneyo zetsimbi.Ineempawu zokwandisa ubushushu obuhambelana nezo zeglasi eqinileyo.Isetyenziselwa ukudityaniswa kokwandiswa okuhambelanayo phakathi kwesinyithi kunye neglasi okanye iiseramikhi.
I-4.Kovar ingxubevange yi-vacuum enyibilikisiweyo, i-iron-nickel-cobalt, i-alloy yokwandisa i-low-expansion alloy ukwakheka kweekhemikhali kulawulwa ngaphakathi kwemida emxinwa ukuze kuqinisekiswe iipropati ezichanekileyo ezifanayo zokwandisa i-thermal.Ulawulo olubanzi lwekhwalithi luqashwe ekwenzeni le ngxubevange ukuqinisekisa iipropati ezifanayo zomzimba kunye nezomatshini ukuze kube lula kumzobo onzulu, ukunyathela kunye nomatshini.

Indawo yeSicelo seKovar Alloy:

● I-alloy ye-Kovar isetyenziselwe ukwenza izitywini ze-hermetic kunye neeglasi zePyrex ezinzima kunye nezixhobo ze-ceramic.
● Le alloy ifumene ukusetyenziswa okubanzi kwiityhubhu zamandla, iityhubhu ze-microwave, ii-transistors kunye ne-diode.Kwiisekethe ezidibeneyo, isetyenziswe kwi-flat pack kunye ne-double-in-line package.
