Txheej Txheem Cej Luam Khoom

4J45 hlau hlau yog ib qho kev tswj hwm thermal expansion Fe-Ni alloy uas muaj kwv yees li 45% nickel. Nws yog tsim los rau cov ntawv thov uas xav tau kev ruaj khov ntawm qhov ntev thiab hermetic sealing, tshwj xeeb tshaj yog qhov twg thermal compatibility nrog iav lossis ceramic yog qhov tseem ceeb. Cov khoom siv no zoo tagnrho rau kev siv hauv semiconductor lead frames, sensor housings, thiab high-reliability electronic packaging.
