1.Kovar ine yakashandiswa zvakanyanya muindasitiri yemagetsi, senge simbi simbi dzakasungirirwa kumahamvuropu akaoma egirazi. Idzi nhengo dzinoshandiswa pamidziyo yakadai sesimba machubhu uye X-ray machubhu, nezvimwe.
2.Mu semiconductor indasitiri kovar inoshandiswa mune hermetically chisimbiso mapakeji kune ese ari maviri akabatanidzwa uye discrete wedunhu michina.
3.Kovar inopihwa mumhando dzakasiyana siyana kuti igadzirise kugadzirwa kwakanaka kwezvikamu zvakasiyana zvesimbi. Iine kupisa kwekuwedzera maitiro anoenderana neaya egirazi rakaomarara. Inoshandiswa pakuenzanisa majoini ekuwedzera pakati pesimbi negirazi kana ceramics.
4.Kovar alloy ivhu rakanyungudika, iron-nickel-cobalt, yakaderera yekuwedzera alloy ine makemikari akaumbwa anodzorwa mukati memiganho yakamanikana kuvimbisa chaiyo yunifomu yekuwedzera yekuwedzera zvivakwa. Yakadzama mhando dhairekitori anoshandiswa mukugadzirwa kweichi chiwanikwa kuona yunifomu yemuviri neyemuchina zvivakwa kuti zvive nyore mukudzora kwakadzika, kutsika uye machining.

Kovar Alloy Chikumbiro munda:

● Kovar alloy yakashandiswa kugadzira hermetic zvisimbiso pamwe neakaoma Pyrex magirazi uye zvedongo zvinhu.
● Ichi chiwanikwa chakawana kushandiswa kwakakura mumagetsi machubhu, ma microwave machubhu, transistors uye diode. Mumatunhu akapindirana, yanga ichishandiswa pakapfava kurongedza uye iwo maviri-mu-mutsara package.
