Tsawg Expansion Alloy Hlau 4j50 Nickel Hlau Alloy 52 / Feni52 Coils Hlau
Alloy 52 Muaj 52% npib tsib xee thiab 48% hlau thiab yog siv dav hauv kev lag luam kev sib txuas lus.Nws kuj pom ib daim ntawv thov nyob rau hauv ntau yam kev siv hluav taws xob, tshwj xeeb tshaj yog rau cov iav seals.
Alloy 52 yog ib qho ntawm cov iav rau hlau sealing alloys tsim los siv nrog ntau hom iav mos. Paub txog cov coefficient ntawm thermal expansion uas yuav luag tas li mus txog 1050F (565 C).
