Sei Inconel Kovar ?
1.Kovar ine kushandiswa kwakakura mumagetsi emagetsi, zvakadai sezvikamu zvesimbi zvakasungirirwa kumavhopupu egirazi yakaoma.Izvi zvikamu zvinoshandiswa kumidziyo yakadai semachubhu emagetsi uye X-ray machubhu, nezvimwe.
2.Mu semiconductor industry kovar inoshandiswa mu hermetically sealed packages for both integrated and discrete circuit devices.
3.Kovar inopiwa mumhando dzakasiyana-siyana kuitira kuti zvive nyore kugadzira zvikamu zvakasiyana-siyana zvesimbi.Iine maitiro ekuwedzera ekupisa anofanana neaya egirazi rakaoma.Inoshandiswa pakubatanidza majoini ekuwedzera pakati pesimbi negirazi kana ceramics.
4.Kovar alloy is vacuum yakanyunguduka, iron-nickel-cobalt, yakaderera kuwedzera alloy iyo makemikari anoumbwa anodzorwa mukati memiganhu yakamanikana kuvimbisa chaiyo yunifomu yekupisa yekuwedzera zvinhu.Yakakura yehutongi hwehutongi hunoshandiswa mukugadzira iyi alloy kuve nechokwadi cheyunifomu yemuviri uye michina zvivakwa kuti zvive nyore mukudhirowa kwakadzika, kutsika uye machining.
Kovar Alloy Application field:
● Kovar alloy yakashandiswa kugadzira hermetic seals neiyo yakaoma magirazi ePyrex uye zvinhu zveceramic.
● Iyi alloy yakawana kushandiswa kwakakura mumachubhu emagetsi, microwave tubes, transistors uye diode.Mumaseketi akabatanidzwa, yakashandiswa kune flat pack uye maviri-mu-mutsara package.
