4J36, yomwe imadziwikanso kuti Invar 36 alloy, ndi yamtengo wapatali, yotsika kwambiri yachitsulo-nickel alloy ndi ultra-low coefficient of expansion (CTE); ili ndi mzere wocheperako wocheperako pakukulitsa kutentha kwapakati pa 20-100 ° C. 4J42 alloy ili ndi coefficient yowonjezereka ya kutentha kwapakati (CTE) yomwe imagwirizana ndi galasi lolimba, galasi lofewa, ndi zoumba.

Aloyi 4J42 ndi aloyi yachitsulo-nickel yokhala ndi coefficient of expansion, coefficient of thermal expansion (CTE) imagwirizana ndi galasi lolimba, magalasi ofewa, zoumba, ndipo akhoza kusindikizidwa mwachinsinsi kudzera muzitsulo zosindikizira magalasi mpaka zitsulo kuti akwaniritse ma CD osindikizidwa; Kutsekedwa kwa CTE kwa alumina omwe amagwiritsidwa ntchito kawirikawiri, oxidative plated LTCC, ndi zigawo za AlN circuit board; okwana maginito mphamvu ndi zabwino kwambiri magetsi katundu; ndi makina abwino, plating, ndi soldering katundu.
