4J32 alloy rod ndi Fe-Ni controlled expansion alloy, yopangidwa mwapadera kuti ikhale yosindikiza magalasi ndi zitsulo ndi ceramic-to-metal. Kukula kwake kwamafuta kumafanana kwambiri ndi magalasi ena olimba ndi zoumba, kuwonetsetsa kukhazikika bwino komanso kudalirika.

Alloy iyi imapereka makina abwino, magwiridwe antchito okhazikika akukula kwamafuta, komanso mawonekedwe odalirika amakina, kuwapangitsa kuti azigwiritsidwa ntchito kwambiri pamapaketi a semiconductor, zida za vacuum, ma relay, masensa, zida zammlengalenga, ndi zida zamagetsi.
