1.Kovar e na le tšebeliso e pharaletseng indastering ea lisebelisoa tsa elektronike, tse kang likarolo tsa tšepe tse kopantsoeng le lienfelopo tsa khalase e thata.Likarolo tsena li sebelisetsoa lisebelisoa tse kang li-tubes tsa matla le X-ray tubes, joalo-joalo.
2.Ka indasteri ea semiconductor kovar e sebelisoa ka har'a liphutheloana tse tiisitsoeng ka hermetically bakeng sa lisebelisoa tse kopantsoeng le tse sa tloaelehang tsa potoloho.
3.Kovar e fanoa ka mefuta e sa tšoaneng ho etsa hore ho be bonolo ho etsa lihlahisoa tse sa tšoaneng tsa tšepe.E na le litšobotsi tsa ho atolosa mocheso tse tšoanang le tsa khalase e thata.E sebelisoa bakeng sa manonyeletso a ho atolosa a tšoanang pakeng tsa tšepe le likhalase kapa lirafshoa.
4.Kovar alloy ke vacuum e qhibilihisitsoeng, tšepe-nickel-cobalt, alloy e fokolang ea ho atolosa eo lik'hemik'hale tsa eona li laoloang ka har'a meeli e moqotetsane ho netefatsa thepa e nepahetseng ea ho atolosa mocheso.Litaolo tse pharalletseng tsa boleng li sebelisoa ha ho etsoa alloy ena ho netefatsa thepa e ts'oanang ea 'mele le ea mochini bakeng sa bonolo ho taka, ho hatakela le ho sebetsa ka machining.

Sebaka sa kopo ea Kovar Alloy:

● Kovar alloy e 'nile ea sebelisoa ho etsa litiiso tsa hermetic ka likhalase tsa Pyrex tse thata le lisebelisoa tsa ceramic.
● Alloy ena e fumane ts'ebeliso e pharaletseng ho li-tubes tsa matla, li-microwave tubes, transistors le diode.Lipotolohong tse kopaneng, e 'nile ea sebelisoa bakeng sa pakete e bataletseng le sephutheloana sa li-in-line tse peli.
