Kev piav qhia dav dav
Kovar yog ib qho nominal 29% Ni-17%Co-54% Fe alloy uas yog lub npe nrov iav-sealing alloy haum rau sealing rau cov iav tawv. Kovar muaj qhov nominal expansion coefficient ntawm kwv yees li 5 ppm / degree thiab inflection kub ntawm ~ 450 degree (840 degree F).
Kovar (ASTM F15) tau siv los ua hermetic seals nrog Pyrex tsom iav thiab cov khoom siv ceramic. Cov hlau no tau pom dav siv hauv cov raj fais fab, microwave tubes, transistors, thiab diodes. Hauv kev sib xyaw ua ke, nws tau siv rau lub pob tiaj tus thiab cov pob khoom dual-hauv-kab.
