4J33 alloy hlau yog qhov tsawg-expansion Fe-Ni-Co alloy khoom tshwj xeeb tsim rau hermetic iav-rau-hlau sealing daim ntaub ntawv. Nrog kwv yees li 33% npib tsib xee thiab ib qho me me ntawm cobalt, cov hlau no muaj cov thermal expansion coefficient zoo sib xws rau cov iav tawv thiab ceramics. Nws yog dav siv nyob rau hauv kev tsim cov tshuab nqus tsev vacuum, infrared sensors, hluav taws xob relays, thiab lwm yam khoom siv siab.
